"what i don't like is the very loud continuous beep it makes when it gives you the reading which i find extremely annoying so it certainly can not be used discreetly"

"so as the reading doesn’t change after you’ve gone over the drink drive limit it isn’t the product for me"

"there is a pack of fifteen blow tubes provided in the kit to be honest i'm sure there is no reason why these can't be washed & used again if rinsed thoroughly"

"the main negative is it didn’t show an increased reading between one glass of wine and three with a break in between for the alcohol to get into my system "

"when someone has a different view to yours about the meaning of "just a small one"and insists that they are legal to drive it is easier to persuade them otherwise when you bring out this useful device to prove they are not"

"it would be nice to see a reusable mouthpiece or non plastic mouthpieces going forward"

"my dad owns the pub and this alcohol tester was really helpful for lads who take some drinks and check the level to find out if they are under the limit"

"also has loads spare mouthpieces "

"pop in the included batteries and attach a tube wait till it says blow then blow"

"i wouldn’t say it’s expensive price is very affordable"

"seems to be a great piece of kit unsure of the accuracy but would seem to be there or there abouts in terms of readings and in line with publicised levels"

"i would not use it on a night out to see if i was ok to drive a drink i would just not drink at all if i was driving"

"35 do not think about driving!"

"04 which is below the limit but if anything had happened could have been held against me if i had driven and had an incident"

"2 wait while it pre heats 3 either wait for the countdown to get to 0 or briefly press the on button during the beep beep countdown 4 blow while it beeps solidly"
