    I decided to give this product a trial run before using it after a night on the town. After having a few beers at the house, I decided to give it a try. I got different reading ranging from 0.04-0.12. I wouldn't trust this product

      Please ensure you are waiting 15 minutes before testing yourself as before that time, the alcohol vapors in your mouth and throat are very high and can lead to wild fluctuations in readings. If you are doing this and still getting inaccurate results, please contact BACtrack Customer Service. All our breathalyzers are covered by a 1 year warranty.

    Doesn't work at all. I had one sip of my first drink and I blew a .16 and then later after two drinks I was blowing .09. Novelty item which is not to be taken seriously and gives different results every time. Don't waste your money.

    I bought this for an idea on a baseline bac number. We have been all over the place after following all instructions and this thing, to us, is nothing more than a party favor. I will spend more money next time.
