    I will say it came in handy when it worked, but it lasted about a month. I went to use it one day and the screen lit up with nothing on it. It just stopped working. What can you expect for 30 dollars.

    Bought this as a stocking stuffer for my husband for Christmas. Although we followed all directions, it never gave us the same reading twice, and the readings it did give varied greatly. (I had 1/2 a wine cooler and I was a .09. My husband had 3 beers and was a .04, then a .02 15 minutes later.) I will try to exchange this one for a different one because if it were to work, it could be useful someday.

      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 inaccurate readings. If you are doing this and still getting inaccurate results, please contact BACtrack Customer Support. All our breathalyzers are covered by a 1 year warranty.

    I’ve used this a few times now and every time i seem to get a different read, it definitely is sensing the alcohol but it isnt the most accurate.

    Handy to estimate your BAC for safety. Occasionally takes a couple of tries to get it right.

    Yes this device works; whether it's exact or not, I don't know. Tried it at a party after several drinks and it barely registered alcohol (did eat food too though). This device, added to good old common sense, is probably a good thing. But if you think you had too much to drink, you probably did. This device is then an afterthought.

    This is a really fun distraction at parties and get togethers with drinking involved. However, the machine becomes really inaccurate after just a few uses. Be sure to buy extra mouth pieces! All in all, a fun thing to carry with you for weddings / social outings.
