"very disappointed"

"i got this oximeter as a back up for a more expensive one i have"

"this was a very expensive oximeter"

"do not waste your money"

"waste of money"

"often inaccurate pulse takes very long time to give a proper oxygen reading"

"not really sure of whether or not this is accurate i bought for my child who has severe asthma but just couldn’t rely on it due to the variations in numbers when checking for eg we put it on and it said spo2 was 89 then we tried again and it was 95 so not reliable enough for my use although seemed a bit more reliable on adult fingers"

"total waste of money!"

"so misleading to put it in sleeping category as there is no way you fall asleep with that siren"

"guys this is very inaccurate i’ve tested this i hardly ever write reviews but i felt like i need to"

"recently i was quite poorly so it was helpful to be able to monitor my responses and be able to give those details to my doctor"

"not a well made item the battery cover was very flimsy"

"absolutely useless!"

"i bought this as my wife suffers from atrial fibrillation and we wanted something to quickly and discretely check if her pulse was fluctuating wildly when she felt she was in one of her af episodes"

"i cant even return to much faffing just to return feel robbed"

"i have breathing and hypertension problems and need to keep a check and record of my heart pulse rate and my respiration!"

"as a light smoker & trying to give them up i tested it before having a cigarette and afterwards and seeing the difference in oxygen levels is such a huge incentive to quit smoking"

"uncovered an unexpected cardiac problem that is now being investigated"

"dont leave it until it's too late"

"i bought it as this time last yr had bad bout of pneumonia this week feb 2020 had bad chest infection with the product i could tell with sat result if was poss more serious than just chest inf also now if having to call for a appt at the docs or that stupid 111 line mention your sats are low with exact figure you will get a immediate response great item esp with holder and lanyard can keep with you to check where ever you are if feeling unwell inc anyone else very handy to have"

"the product is wonderful i was rushed into hospital when my oxiygen level dropped to 45 an i was very badly struggling to breath i was on oxygen in hospital for a week and felt pretty scared on returning home as i live by myself and i am 77 years young buying the oximetry gave me the confidence i needed"

"in the morning having yet another cardiac event not being able to breathe and thinking this time was the end"

"unfortunately this product does not assist in this monitoring process because of inconsistent readings and is therefore unreliable"

"product is rather pricey probably should be a quarter of the price"

"the device automatically shuts itself off after a few seconds of non use"

"alarm sounds if level below 95 this is a bit annoying until levels stabilise and sounds cease"

"very disconcerting"

"works well takes a while to get a reading not to long but longer than i was expecting but really handy got it for my dad who has had health problems this year and his heart races sometimes so a good way of keeping an eye on him when he's not to good"

"i bought this as i’ve been severely ill over the last few months have had a couple of operations and am writing this review from my hospital bed this pulse oximetry is as accurate as you can get it has alerted me to my pulse drop and low blood oxygen saturation i’m in hospital with early signs of sepsis receiving antibiotics you can buy with confidence i bet my life on it 5 stars if not more"

"will be returning this"

"tiny niggles would be that it presses down on your finger a bit too firmly and it starts beeping an alarm if the pulse goes over 130 or below 50 or if the oxygen level goes below 94"

"it has been very useful in the past when i've had to describe show to doctors or my boss that i'm having severe chest pain"

"however it’s extremely fiddly and it often doesn’t provide a reading of any sort unless you have 6 or 7 attempts and then it seems to spring into action"

"turns out if your heartrate is 124 whilst sitting still people actually take you seriously and finally refer you to cardiology after 2 years of complaining of sporadic chest pain shooting pain in my neck and left arm"

"these readings were taken two minutes apart and are obviously incorrect!"

"perfect little oximeter"

"i bought this as i’ve been severely ill over the last few months have had a couple of operations and am writing this review from my hospital bed this pulse oximetry is as accurate as you can get it has alerted me to my pulse drop and low blood oxygen saturation i’m in hospital with early signs of sepsis receiving antibiotics you can buy with confidence i bet my life on it 5 stars if not more"

"i got this for my 1 year old who’s on oxygen and it’s hard to read his finger as takes too long once i have him settled and it’s not accurate it was saying his sats were 82% then the nurse checked and he was 94%"

"as i suffer from angina i am always checking my pulse to put my mind at ease"

"the cover of the batteries broke straight away but overall im still very happy with this product"

"i have replaced the batteries twice but still get either no result after 5 minutes or these inaccurate readings"

"accuracy unknown but consistency very high"

"the only disappointing feature was that there was no blood pressure waveform displayed only the instantaneous blood pressure"

"i’ve tested this against hospital ones and it’s wrong especially the oxygen levels are wrong please be careful with this one"

"i purchased this product for my husband who suffers with ipf"

"nothing to dislike about it"

"i compared the pulse rate results to a fitness watch and they average out the same so i'd assume this is accurate"

"i notice it doesn’t work when my finger is cold"

"i have replaced the batteries twice but still get either no result after 5 minutes or these inaccurate readings"

"constantly gives inaccurate readings"

"this is very inacurate people would think they dying using this"

"the lights come on and you can see it attempting to work but alas no reading appears"

"accepting it’s not an expensive item i can’t recommend"

"i bought it as this time last yr had bad bout of pneumonia this week feb 2020 had bad chest infection with the product i could tell with sat result if was poss more serious than just chest inf also now if having to call for a appt at the docs or that stupid 111 line mention your sats are low with exact figure you will get a immediate response great item esp with holder and lanyard can keep with you to check where ever you are if feeling unwell inc anyone else very handy to have"

"i believe this is a temporary problem until it is broken in"

"and all that’s going on with the coronavirus i had suffered with the coronavirus and had still had it on my lungs after two months so to monitor my oxygen i’ve got one of these then my neighbour asked for one then the lady down the road asked for one and then i bought one for my mum this is brilliant"

"i got this for my 1 year old who’s on oxygen and it’s hard to read his finger as takes too long once i have him settled and it’s not accurate it was saying his sats were 82% then the nurse checked and he was 94%"

"defeats it usually no reading shows"

"it only had conection problems about 3 times during this 3 months and i am using i one to 15 times a day"

"only for one us us it showed 100 a couple of times after pressing so hard on the infra red rays!"

"the readings were inconsistent and i did not have sufficient confidence to keep this product as it does need to be accurate in as much as consistency is important"

"inaccurate readings that fluctuate widely with each reading hence not accurate"

"this has taken so much stress away from checking over my heart warrior"

"wasn't sure how accurate this would be mixed amazon reviews but have tested against the similar metres used in my cardio rehabilitation programme and the one used by the hospital heart function clinic and it gave exactly the same results"

"whilst this does quickly report the pulse and updates the pulse quickly it has one major drawback"

"what’s not to like!"

"personally i find that the oxi 27 grips my finger a little too tightly and after a few minutes becomes very slightly uncomfortable and hence i have deducted a star from the rating it may be that the hinge & spring loosen up a bit after a bit of usage but for the time being it just feels a little too tight and i would say i have average sized fingers"

"it works intermittently so would not buy again"

"i have had 2 or 3 oximeters over the years but have never had one as poor as this"

"im afraid this came with some minor damage to the battery cover meaning the cover keeps popping open"

"the beep alerts you to a drop in oxygen mind dropped a couple of times so i will be using this often to monitor my health"

"it has an alarm feature that emits a loud beep if the pulse goes below 50 bpm"

"i can only assume it is accurate as my own oxygen levels read okay so i assume the same goes for his reading"

"gives some indication of stress to enable reaction against that also shows when deep breathing is required to increase oxygen blood level"

"the problem with this is once you put it on your finger and your oxygen goes to a certain level than a massive beep keeps going off"

"i lost my partners old one so i have replaced it with this one"

"came out of hospital and needed cheap o2 meter to monitor levels excellent device i’d recommend but it didn’t arrive on time"

"exactly as advertised"

"can't fault it for the price"

"i bought it as this time last yr had bad bout of pneumonia this week feb 2020 had bad chest infection with the product i could tell with sat result if was poss more serious than just chest inf also now if having to call for a appt at the docs or that stupid 111 line mention your sats are low with exact figure you will get a immediate response great item esp with holder and lanyard can keep with you to check where ever you are if feeling unwell inc anyone else very handy to have"

"works well takes a while to get a reading not to long but longer than i was expecting but really handy got it for my dad who has had health problems this year and his heart races sometimes so a good way of keeping an eye on him when he's not to good"

"she isn't medically trained but that does not matter as this is so easy to use"

"the screen is bright with all the info you need clearly laid out"

"a lot of care has been put into the packaging of the product so it doesn't feel cheap at any point during the unboxing"

"it is a monochrome display showing only in bright red something which i haven't found disturbing"

"unfortunately i have nothing else to test oxygen levels but it was reporting what i expected so again feel this to be accurate"

"tiny niggles would be that it presses down on your finger a bit too firmly and it starts beeping an alarm if the pulse goes over 130 or below 50 or if the oxygen level goes below 94"

"the lights come on and you can see it attempting to work but alas no reading appears"

"a month ago i bought a wrist watch type monitor but had to return it because it was so inaccurate mind you it was only 25 quid "

"i’ve read & reread the instructions very carefully about how my finger should be placed in the device to ensure a reading and still routinely encounter the problem"

"by pressing the red button the device is switched on"

"however it’s extremely fiddly and it often doesn’t provide a reading of any sort unless you have 6 or 7 attempts and then it seems to spring into action"

"i would reccomend this to anyone"

"would purchase from same trader again"

"i’ve have a problem with my blood oxygen saturation and have found this product invaluable"

"personally i find that the oxi 27 grips my finger a little too tightly and after a few minutes becomes very slightly uncomfortable and hence i have deducted a star from the rating it may be that the hinge & spring loosen up a bit after a bit of usage but for the time being it just feels a little too tight and i would say i have average sized fingers"

"just as it was advertised"

"very disappointed"

"works as well if not better than some of the more expensive models"

"early on when i was first diagnosed with copd i lost a very expensive one outside somewhere"

"don’t waste your money"

"the batteries have lasted a very long time haven't needed to change them yet after many many uses"

"i'm very sorry i bought this it's a waste of money and now i have to find another one"

"once in urgent care we had an inaccurate reading that resulted in an unnecessary trip to the er which is one reason i was prompted to get our own"

"complete waste of money and terrible customer service"

"i am a healthcare provider and find this thing a disappointing waste of money"

"total failure after 4 months of use is unacceptable"

"this is what we used when we came down with corona virus"

"but it is so wildly inconsistent that it is practically worthless"

"it takes forever and is inaccurate when the result finally pops up"

"a few seconds later they can drop back to 95% the expected value"

"told me to dispose of faulty oximeter "

"i’m not sure if i just received a defective product but i will be returning it"

"it was packaged carefully with a piece of foam to cushion it"

"complete waste of money and terrible customer service"

"you need to rest your hand on the table and give it a few seconds to get the highest reading"

"i give up with this junk"

"lowered oxygen saturation is an important symptom of a covid 19 viral infection"

"and even then the devices flashes something on the screen and then shuts off"

"i can't believe i wasted money on this!"

"the insides are slippery so that it falls off your finger"

"in this uncertain covid era we learned it was wise to have an oximeter on hand to measure oxygen levels"

"my dad has lung issues and requires oxygen"

"the pulse oximeter i received was poorly made"

"it is very easy to use and the readings don't take long 45s to stabilize for me which really just gives me peace of mind since it's been diificult for my family to obtain covid tests"

"with all of the covid headlines in these scary times i ordered this after reading an article that said you could take care of yourself at home as long as your oxygen level did not dip below 90 for too long"

"both have the same issue"

"i just feel better knowing this piece of fab"

"this can in very handy in determining if the shortness of breath was causing any significant decrease in oxygen levels"

"the only issue i've had with it is that it's sometimes hard to find the "sweet spot" where it can see your pulse and start measuring"

"a thermometer is a fine tool but i wanted an easy and reliable check for oxygen saturation the canary in the coal mine for coronavirus purposes"

"but it is so wildly inconsistent that it is practically worthless"

"comes with silicone cover that is a little loose so it doesnt always stay on"

"bought for my son who lives in another state and has a lung condition during the covid scare"

"if we should notice a significant decline we’ll know it’s time to call for information as to what to do next"

"the oximeter will not register properly once the weather has become colder"

"either i’m really having oxygen deprivation or the oximeter doesn’t work"

"this little device is going to come in handy for physical fitness training as well as to keep on hand for covid concerns"

"don't waste your money unless you don't mind disposable products"

"i am an unfortunate victim of lung disease"

"absolute junk"

"the only complaint i would have is the rubber case it's flimsy and falls off easily but you don't really need it"

"readings are a bit more noisy than i would like as is typical with these instruments"

"i don't know if it's me or my heart perhaps i have undiagnosed problems or the machine but the pulse oximeter will initially read a pulse of say 75"

"knowing your decline of blood oxygen and being able to report it in your application will assist in your eligibility"

"let me be honest: being chronically ill in your 20’s isn’t the greatest and it’s weird to get this excited about a pulse ox"

"they say that covid 19 doesn’t seem to cause shortness of breath even with low oxygen numbers so this appears to be a great way to check how your lungs are working if you are feeling sick"

"with everything going on these little babies suddenly skyrocketed price wise"

"wasn't sure if my shortness of breath was health covid or mental anxiety related"

"product failed only after a few months of usage"

"spoiler alert"

"the only problem i have is the new one does not always come on or will go out right away before a reading has shown"

"changed the batteries and wiped down according to instructions but still no luck"

"i bought this product because in the following week i became sick and was having trouble breathing"

"i looked at the negative reviews 1st most seemed to be happenstance of getting a defective device"

"something about covid 19 keeps victims from feeling distress until it is too late"

"i guess i should have saved my money and gotten one of the cheap ones because this unit is not that accurate"

"after 2 mile walk is 95 and upon rest in low 70s but jumps around"

"i do expect an inaccurate meter to slip through but the worst part was the company's response that i shouldn't expect it to be accurate for the price"

"other medical products i've bought during covid times have come with very choppy english instructions"

"once i received the product i put battery on and immediately tested with my right index finger and it would not give a reading for a while i tried different position where i insert my finger different finger face up and face down it would eventually gave a reading but it was a painful wait"

"wasn't sure if my shortness of breath was health covid or mental anxiety related"

"when they are having a panic like attack they can use this thing and see that their oxygen level is ok thus revealing their stress"

"since it is so inaccurate it is entirely useless"

"i bought this product because in the following week i became sick and was having trouble breathing"

"this is a useful tool to have when you are sick especially during this pandemic!"

"regardless i definitely recommend this product pandemic or otherwise :"

"as someone that lives with chronic asthma it's a good idea to have one of these meters handy"

"it is important because if your blood oxygen leave falls below 90 then you should contact a medical practitioner"

"just make sure you sit down and rest for a minute or so before using otherwise your readings will be higher than anticipated logically right?"

"same problem or worse"

"when they are having a panic like attack they can use this thing and see that their oxygen level is ok thus revealing their stress"

"i am healthy with no lung conditions and depending on the finger i use and how i hold the unit i get an oxy level of anywhere from 92% to 98% the key to using this for covid lung impairment is to get a baseline under the same conditions same finger hold the unit still and in the same position & it will give you adequate day to day relative accuracy for one set of conditions i get between 94 96% "

"with the need to wear masks in public as an older person i have been concerned about my oxygen levels and wanted to be able to track them and see how much of an effect the masks were having on my o2 levels and thus my health"

"i do wear nailpolish"

"its readings are inconsistent sometimes a full 8 to 10 points lower than actual oxygen saturation levels"

"my husband's was 97 and he has never smoked but has some congestion going on"

"i know a lot of these oximeters are junk but i read some reviews and thought this brand would be better"

"i have diabetes and am 70 years old"

"but i normally take my reading after a minute or more"

"in between those instances i bought this and took it to one of my doctors offices to compare for accuracy but ended up not taking it out of my bag once i saw my doctor using the exact same model"

"i re ordered because it was one of the few oximeters that was back in stock after the pandemic and it was my hope that they had fixed the issue that caused it to stop working"

"i changed the batteries hoping it was a battery issue"

"the point i subtracted was for the unnecessary “free ” poorly constructed silicone sleeve"

"if i still had box u would return it"

"like almost everything i purchase made in china there are little particles and small pieces of cardboard ?"

"i have had incidents of exercise associated collapse eac and exercise associated postural hypotension eaph with symptoms like dizziness if i change my speed too quickly say from running to a stop "

"unfortunately i started to use it after the return window lapsed so off the the trash it goes"

"for my purposes it does the job but if minor variations in blood o2 levels are a life and death matter one should of course not rely on this item"

"this oximeter is small weightless accurate and reads so much faster than the facility's machine"

"the zacurate oximeter looks like a high quality piece of electronics it's robustly built rather than flimsy plastic and works as well as any that i have seen in medical use"

"the sats seem about a half second more responsive than on my nonin"

"if you're in a vehicle walking or in some other way moving or bouncing around it doesn't stay clipped on your finger sometimes and it can take a while to get it positioned right to get a good reading"

"it started off well worked for about a month and then stopped working"

"low levels can also point to sleep apnea problems"

"don't waste the money"

"it shouldn't be this unreliable especially when you need it during an emergency"

"little ones 4 7 is affected as well because they panic after a while and their breathing becomes erratic and they feel the need to remove the mask"

"this second one came quickly as stated"

"barely good for scratch resistant and doesn't prevent the power button from accidentally activating"

"i’m guessing one was messed up or something"

"tendency is to use the index finger but was told by a medical tech that's not always the best finger to use since the skin in often thicker on those digits"

"the one the va sent me broke in the first week"

"but about two weeks ago it started getting flaky and now it is not reading my pulses at all"

"additionally there was some optional minor assembly—attaching the lanyard—that was a little harder than expected because of my arthritic hands"

"lowered oxygen saturation is an important symptom of a covid 19 viral infection"

"especially after hearing about people walking into the er feeling “just a little bit off” yet finding out their saturated o2 should have been clinically dead😳 yikes!"

"also the battery indicator is an empty icon that does not show battery life left available"

"i'm sending it back!"

"i bought this to supplement my bp monitor and i must say it gives additional info the bp cuff monitor does not"

"simple one button operation"

"hope we don’t need it again anytime soon"

"degradation of lung function is one of the first signs of covid without symptoms"

"even though he has retired i still wanted to replace it and most especially during this coronavirus pandemic"

"when my pulse goes up it reads immediately instead of 30 seconds later"

"occasionally it simply will not work"

"it also seemed to be slow to register but that may have just been my finger"

"if it’s accuracy you’re looking for with a less healthy patient rely on your local hospital’s er equipment"

"little ones 4 7 is affected as well because they panic after a while and their breathing becomes erratic and they feel the need to remove the mask"

""bos" can be one of the first body conditions to alter if a person is infected with covid19 even before a fever might occur the blood oxygen saturation can start to drop"

"the lanyard was attached and the device was simply just tossed smashed into the box then sealed up"

"for paranoid hypochondriacs like me or anyone who likes to stay alive this pulse oximeter is a critical addition to your medicine cabinet"

"this is a piece of junk"

"she had double pneumonia and didn’t even know it"

"barely good for scratch resistant and doesn't prevent the power button from accidentally activating"

"the device was showing inaccurate numbers oxygen 64 for example"

"the less bars the less accurate and the more bars the more accurate your reading is"

"still not reliable"

"i do expect an inaccurate meter to slip through but the worst part was the company's response that i shouldn't expect it to be accurate for the price"

"no doctor has ever found heart trouble so "

"i’m very familiar with that as an issue with pulse i i meters and it has not been the problem when it is slow to show a reading"

"also it comes with a plastic shell clam like flexible cover"

"i think that most older persons should have access to an instrument like this to check breathing and physical exertion blood oxygen"

"add a million companies selling them with few reviews and i nearly gave up"

"it's gonna take forever to read"

"for a while i blamed that on my elderly residents we have to check pulse ox's every shift now due to covid and it's time enough without the oximeter giving trouble but then i tried that on myself and although i am also elderly in my mid sixties i am strong healthy and still practicing as a registered nurse"

"all in all a very unreliable oximeter"

"the lanyard was attached and the device was simply just tossed smashed into the box then sealed up"

"first i should point out that my “accuracy “ rating is totally arbitrary how should i know how accurate it is?"

"i am healthy with no lung conditions and depending on the finger i use and how i hold the unit i get an oxy level of anywhere from 92% to 98% the key to using this for covid lung impairment is to get a baseline under the same conditions same finger hold the unit still and in the same position & it will give you adequate day to day relative accuracy for one set of conditions i get between 94 96% "

"i am not only using this for my covid 19 preparation kit but also during exercise"

"just flickers on and off"

"it is easier to read than the ones that we used at a hospital where i was working when covid 19 arrived"

"as covid 19 spreads this device can tell you if your blood and other organs are getting enough oxygen"

"i recently started to have certain health issues with some extremely low bp and getting to the point of passing out if i didn't reach for the chair i did some research and learned that with some low bp cases the blood is lacking oxygen and therefore is not supplying oxygen to vital organs"

"we knew that dropping blood oxygen levels were a bad sign so we used it to track these levels to alert us if there was a turn for the worse"

"i ran a few crude tests with and without the mask and found there was very little change"

"so i am using this oximeter to measure my spo2 levels throughout my exercise routine"

"i purchased this as a way to track if i or my family are experiencing covid related hypoxia"

"got it in preparation for the covid19 pandemic and thought it would sit around in my medicine cabinet "

"turns out they were reading it upside down which can easily be mistaken"

"one reported major side effect of covid19 infection is the problematic reduction in one’s lung’s ability to absorb oxygen"

"we knew that dropping blood oxygen levels were a bad sign so we used it to track these levels to alert us if there was a turn for the worse"

"conclusion: zacurate is within the standard margin of error"

"one died and one is really messed up"

"most likely my finger was positioned incorrectly"

"i just need to be a little patient while the readings stabilize"

"it reads low and if a person were to make a decision to go to the er or not based on the reading they would have unnecessary worry and would possibly be making an unnecessary trip to the hospital"

"for my purposes it does the job but if minor variations in blood o2 levels are a life and death matter one should of course not rely on this item"

"i don't know if it's me or my heart perhaps i have undiagnosed problems or the machine but the pulse oximeter will initially read a pulse of say 75"

"other medical products i've bought during covid times have come with very choppy english instructions"

"when my pulse goes up it reads immediately instead of 30 seconds later"

"but this is stated in the docs and what i expected at this price point"

"changed the batteries and wiped down according to instructions but still no luck"

"i hoped for a better produce but this model is useless!"

"compared to my doctors fingertip monitor"

"these studies reveal that even when people have low spo2 levels caused by covid 19 they are totally unaware of it because they are not yet having breathing difficulties"

"fairly accurate so i am puzzled at to the cause of the corrosion"

"i haven't had it very long but am extremely impressed at this point"

"if when that happens we want to at least be prepared for “happy hypoxia” that situation that’s being reported where people become quite ill with low blood oxygens but are unaware they are indeed quite ill"

"when i first put this on i thought i didn't have a good little monitor: the numbers for the heart beat were jumping all over the place 80 120 92 100 etc"

"i bought this just in case someone in my family gets covid 19"

"seems accurate to me but it will not hurt to check"

"i don’t need to keep a record of my readings on an app so it doesn’t bother me that this oximeter does not have an app"

"i looked at the negative reviews 1st most seemed to be happenstance of getting a defective device"

"i didn't rate accuracy as i don't have anything to compare to"

"replaced batteries still not working"

"in today's covid 19 era even though this is not official it allows me to give my stats to my doctor during my telehealth visits"

"also a nit the flimsy silicon case fits but is pretty worthless for adding any utility to the device"

"many are waiting too long and don't even know they have walking pneumonia"

"probably this tool is not accurate"

"i am still using it to establish a benchmark to compare to going forward since i have twice presented low oxygen on a visit to my physician in recent years"

"some of the pulse readings are erratic or completely wrong especially under “cardio exercise” conditions which is the primary reason i purchased the unit for"

"with all of the covid headlines in these scary times i ordered this after reading an article that said you could take care of yourself at home as long as your oxygen level did not dip below 90 for too long"

"the shipping was a lot faster than i expected considering the pandemic and distribution issues"

"a simple ten second or so test just by putting this little item on your finger will tell you either your fine or you need to go to a hospital immediately if the number goes too low"

"i'm putting together a "covid 19 care kit" for my home in the event that either myself or my husband come down with the virus"

"i have read many articles about the covid 19 virus and one point that stood out to me was the gradual decrease in oxygen flow for older people"

"i use it to spot check target heart rate during workouts or confirm my orthostatic intolerance when i have episodes"

"is not bluetooth compatible and it does not store data so be prepared to record your numbers elsewhere if you are keeping track of them"

"i had accidentally broken my father's pulse oximeter that he carried around the hospital for years as the director of the icu and director of pulmonary services"

"also a nit the flimsy silicon case fits but is pretty worthless for adding any utility to the device"

"this appears to be a fairly decent meter but we were disappointed that the vinyl cover was deformed and it didn't fit very snug on the device"

"i’ve changed the batteries also but it makes no difference"

"i even googled to see if there's a simple way to verify but didn't see anything other than complex medical reports that are way over my head"

"if you happen to come down with covid 19 and you are sent home to recuperate it's important to check your blood oxygen level regularly and report to your doctor if your number falls below 95"

"these studies reveal that even when people have low spo2 levels caused by covid 19 they are totally unaware of it because they are not yet having breathing difficulties"

"one symptom of covid 19 is that it can lower blood oxygen saturation slowly over time"

"in these cases a person feels fine until they don't"

"i re ordered because it was one of the few oximeters that was back in stock after the pandemic and it was my hope that they had fixed the issue that caused it to stop working"

"falls right off so it’s useless"

"i need accuracy as i have asthma and husband wears mask at work so wanted to ensure his levels are right"

"i've also been told that wearing dark fingernail polish makes the result lower than what it really is but i did not find that the case"

"i guess i should have saved my money and gotten one of the cheap ones because this unit is not that accurate"

"sometimes outward symptoms of low oxygen levels don't outwardly manifest"

"blood oxy level？ if you are under 85% you would have felt hard catch breathing and in an hospital already"

"when i contacted the manufacturer to see if i could exchange this model for an upgrade to a better model they said they would not do that"

"this is something we really wanted with covid 19 being around now so we can get to the hospital before things get really bad"

"i sent my son this oximeter because he was diagnosed with covid"

"for those of you that had yours die the second time you used it i thought i had that problem"

"hopefully i'll never need it"

"so this is a small and great tool to hopefully rid you of nonsense anxiety"

"the manufacturer tried to tell me it’s due to cold hands"

"i ran a few crude tests with and without the mask and found there was very little change"

"the second time it took a very very long time to get a reading"

"battery installation and replacement of the two aaa cells provided is simple as well"

"she had double pneumonia and didn’t even know it"

"more of an electronic toy for psychological sense of security but not a serious medical device"

"so i dont know it will me same or not"

"i would have returned it today but i am past the return period"

"as soon as i put the batteries in this instrument it gave me good readings that i need for general health and to help combat and diagnose covid 19"

"many of them had very low blood oxygen levels and were unaware of it"

"something about covid 19 keeps victims from feeling distress until it is too late"

"i do not understand this"

"i checked this against the professional device at the office and there is really no difference"

"pulse 32 and most of the time not even showing any reading"

"i have no medical background so i can’t comment on that"

"it takes so long to give a measurement i don’t trust it"

"maybe it was a fluke"

"i'm very sorry i bought this it's a waste of money and now i have to find another one"

"other than that i love how quickly the reading take so i don't have to wait very long to get my reading and the pressure seems light compaired to a lot of metters i used"

"all while i am siting calmly and not moving"

"i’m not sure if i just received a defective product but i will be returning it"

"just make sure that your hands are not cold as that will make it much harder to get a reading"

"got it his week was inexpensive enough to be worth buying as a "just in case" we need it thing with all the covid going around"

"the quality of this pulse ox is poor due to its accuracy"

"it's now put away hopefully to never need to use!"

"the inside where the batteries lie was corroded i never take a shower with it "

"o2 sensor functionality: put on the tip of your ring finger press the button and watch "i'm working" lights flash as your o2 level is read once determined your o2 percentage and pulse are displayed in tall easy to read red leds"

"i use to wonder its accuracy but one day i had a very bad flare up"

"there are a few that are a bit cheaper direct out of china and i actually tried ordering from two different companies and after being promised shipping from china in 2 days after purchasing i would get notice that shipping would be 10 15 days"

"this little device is going to come in handy for physical fitness training as well as to keep on hand for covid concerns"

"it reads me very low"

"i get a reading each time and it's easy to use but whether on not it's truly accurate i have no idea"

"first photo was taken on august 15th"

"couldn't be easier"

"o2 sensor functionality: put on the tip of your ring finger press the button and watch "i'm working" lights flash as your o2 level is read once determined your o2 percentage and pulse are displayed in tall easy to read red leds"

"the text size in the manual is very small making it difficult to read"

"i do expect an inaccurate meter to slip through but the worst part was the company's response that i shouldn't expect it to be accurate for the price"

"this one is far too slow and i would like to return it"

"i have asthma and was concerned like many about the current covid 19 reality"

"i make sure to leave it on my finger for at least 20 seconds to get an accurate reading"

"inside the box: easy to read and understand manual even explains how the reader calculates o2 percentage "

"i'm going to purchase more of these for our elderly family members so they can establish a baseline o2 saturation and can better monitor any respiratory symptoms they may be having during illness"

"i almost thought this was some kind of a scam when i bought it because the price was so good for what it is nope"

"it also helped me to understand that my labored breathing under my mask was more psychosomatic than physiological"

"little ones 4 7 is affected as well because they panic after a while and their breathing becomes erratic and they feel the need to remove the mask"

"this one lasted two days i have not yet tried to change the batteries"

"assuming it's accurate but not caring that much because at least i get pulse and ox numbers that help me gauge when i'm better or worse"
