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

Really good. App is easy to use and seems pretty accurate. We’ve tested it with several people and kept track of what each of us have drank and it matches the amount of units very closely. Obviously I wouldn’t recommend using anything if the law depends on you being sober but this is very good for everything else.

Great little device with excellent readngs

I bought this breathalyzer so that I could feel confident the next day when driving after a night of drink. It has also become useful as my teenage daughter has gotten to that age and puts my mind at ease when needed. I've used it both with the app and they stand alone use. Very handy to be able to have both. I would highly recommend it. I feel confident in its results. Point to note.. no food or drink for half an hour before testing to get the most accurate results.

This device absolutely sucks It so bad anytime I. Blow it just say breath steadily no matter if you blow hard soft or even just breath. It does not work Nothing works stay away this is joke product

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.

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 UK 0.036 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

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.

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

Petit appareil d'alco-test et fonctionne très bien. Facile d'utilisation, il suffit de souffler pendant le bip sonore et d'arrêter à l'arrêt de son. Lecture rapide et aussi la fonction de donner le temps à atteindre le 0 alcool est très rapide. De plus essayer de tenter de trouver le taux alcoolémie est très instructif et on en apprend sur notre propre consommation. Je recommande aussi d'acheter le coffret pour le ranger.

Solo espera 20 minutos después de un alimento, bebida o cigarro para que el aparato de una medición precisa, no lo he usado con el celular ya que no es necesario a no ser que quieras tener un seguimiento de tu actividad alcohólica :3

Compact and useful for my teenager who has just come of drinking age. A great tool to keep him safe and help him make the right decision when driving (ie not to when he's over).

A priori está siendo bastante preciso. Las medidas corresponden con lo esperado en función del alcohol ingerido en cada caso. el aparato es muy pequeño y podría perderse, pero es cómodo de llevar encima. se usa con o sin conectar al móvil, pero hay que cambiar cada vez el modo antes de empezar. es mas sencillo usar directamente que con App y la pantalla da el valor de alcohol en aire espirado, horas hasta 0% y algún mensaje adicional.

excellent produit, très efficace et très précis si on l'utilise en respectant les consignes d'utilisation avec rigueur .... je conseille ce produit
