"i purchased this to use to monitor blood oxygen saturation during the covid outbreak"

"i take them with my hand in i pad and they can see how quickly they drop"

"every household should have one of these in the first aid kit no wonder they sold out when covid kicked off"

"it is impossible to comment on the accuracy without calibration tools however based on my last hospital reading it seems to be within the ball park"

"i've changed 5 different batteries and still not working"

"the unit in operation is very jumpy cannot believe that my o2 stats jump about that much"

"in addition to the pulse oximeter the box also contains a soft plastic case to protect the device a material case that i assume can be used to transport the device and a lanyard that attaches to the material case for carrying around the neck another reviewer says it is too short to go over the head but mine is plenty long enough "

"not so good with cold hands not suitable for children"

"not sure about the accuracy as have no way to check hope is ok as new"

"then i put my glasses on and realised my error!"

"only thing i don't like is the screen could be the other way round so you could read it more easily clearly geared to someone else reading it i guess"

"waste of my money unfortunately"

"totally dissatisfied with the product and specially when it comes to know from the marking that it has be manufactured in hubei province in china i felt a bit scared of to think of a used product"

"intermittent display could not get a reading"

"however the issue lays with the seller alleging that once the box is opened the buyer cannot return the item"

"tried it on children and adults and wouldn’t work on anyone"

"so this is a handy tool to have alongside inhalers i wish inhalers provided a cure rather than just symptomatic relief "

"it takes all the gues work out of the situation"

"can take a bit of messing about to get the lanyard cord through the tiny slot on the device but if you have your own definitely consider using it as the cord is very short to tie off"

"had this since april 2016 and only used it occasionaly but tonight it gave one reading wich took a long time to register and there after it stopped"

"i brought it to replace a broken one and it kept saying my o2 sats were 25% and below so it went back!"

"my mother suffers from chronic asthma and c"

"it won’t make you better but you would no that you need to either relax yourself or take medication if your on any "

"having had a recent heart attack i wanted the same machine at home to monitor my heart first class item"

"the product has really helped our family member who caught covid 19"

"don't need the oximeter but it's there as a bonus for anyone who does"

"usually gives no reading at all occasionally manages one eventually but no way to know if it is true"

"on the negative side it doesn't grip the finger very strongly and the seller would appear to be now profiteering i see they have increased the price within the last 4 weeks by 50% i paid just under £30 and it is now just under £45"

"how can i get a replacement organised please as there seems to be no other links that give me this opportunity to request a replacement"

"simply didn't work"

"despite being a long life non smoker i started with asthma at 47 years of age"

"i try to remain reasonably active but the realm of the possible is shrinking down on me"

"if as i suspect it is inaccurate i will return it"

"these work but are slow"

"it is as accurate as the ones used by ambulance crews having had to call them after some bad asthma attacks and compared readings"

"put the batteries and refused to work nor can i read the instructions as the letters are so so small"

"ok but has a tendency to read low then read high so are not shure if the readings are accurate but it gives a more accurate reading the second time it is used checked with hospital unit so will only use as a guide if feeling unwell consult medical help barry"

"not sure about the accuracy but if it is out i don't see this being a problem as its accurate enough for my use which is taking client hr after an activity"

"when compared to a professional monitor it measure quite well but i doubt it is durable since the cheap plastic casing is suspect"

"the item arrived earlier and was a little baffled as the battery compartment has springs which usually means the negative end of a battery goes towards it but not in this case"

"i’ve used it twice and its already stopped working"

"it is very small and not of substantial material"

"the oxygen readings vary wildly between 81 and 96 rendering the product completely unreliable"

"the figure is useful evidence for a doctor that something is wrong"

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

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

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

"waste of money"

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

"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"

"what’s not to like!"

"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"

"very disappointed"

"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"

"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"

"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"

"this was a very expensive oximeter"

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

"very disconcerting"

"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"

"do not waste your money"

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

"i suffer from copd and i do suffer from breathing difficulties sometimes"

"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"

"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"

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

"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"

"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"

"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"

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

"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"

"this has not been our experience"

"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 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 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"

"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"

"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"
