BACtrack C8 Breathalyser, Professional-Grade Accuracy, Optional Wireless Smartphone Connectivity, Compatible w/Apple iPhone, Google & Samsung Android Devices, Apple HealthKit Integration

As a night club medical this pocket device is great to show people how drunk they are. Saves alot of arguments. Tested vigorously on a student night and was solid and reliable. Oozes quality, simple to use and estimated time to sober really handy.

Of course you'll never know how accurate any of these things are without comparing to a genuine police spec breathalyser, and so I intend to follow the advice of not driving unless it shows 0.00. But this seems believable in terms of BAC increase per drink.Bought after my AlcoDigital 7000 went thoroughly unreliable, in spite of the sensor being nowhere near its use limits. It will happily tell me I'm 6 times the legal drink-drive limit after 2 beers. The Bactrack on the other hand registers me as approaching the (England) limit when compared side by side.Buying as a 'morning after' device (I wouldn't drink past the limit and drive the same day) the hours until sober feature is a real boon. I feel it allows me to make an educated decision on whether I can have one more drink tonight. It seems to be pretty linear. If you test 2 hours after it said 4 hours remaining, it'll say about 2.I went for the model that works fully (including hours until sober display) without the app. Worth the extra £20 in my opinion, as that's how I prefer to use the device.

Excellent product, very easy to set it up and link to the app. Would definitely recommend.

Tried and tested, it was so complicated understanding what the measurements mean but finally. IN CLEAR ENGLISH.0.035 or UNDER you can legally drive in UK0.036 or over eg. 0.04 your over the legal limit.0.035 is approx 3.5 alcohol units and you get rid of approx 1 unit per hour but if your a heavy/regular drinker that's quicker

I use this on a regular basis just to be 100% sure, especially if I have to driver earlier than I expected, having been out the night before. I like the fact it actually says how long in minutes and hours before your body is at 0.00. One thing I have noticed is that some inhalers affect the readings though (gives a higher reading) so always test before using an inhaler.

This is great. Simple. However, I would drink water before using as any alcohol in the mouth gives a false high reading.

I wish I’d thought of this before since we are trying to limit or give up alcohol. We are learning how long it takes to leave the system. Of course, alcohol is not good for general health but it is useful to know what’s happening in your own body . Buying an accurate one seems a good idea, which this one is.

Needs more info about how to read it and understand legal drive limits.Took a while to find the info online.A lot smaller than expected.However works well standalone or using the app.
