BACtrack Keychain Breathalyzer (Black) | Ultra-Portable Alcohol Tester for Personal Use

Unfortunately, I bought this product because I am an alcoholic, and I have been having a great deal of difficulty staying sober. My family never believed me when I said I wasn't drinking (even when I was actually telling the truth ha). So I ordered this BACTrack for THEM. What I learned when it arrived was that it helps ME, too. Having that accountability is good and it makes me proud when I blow zeros. The product came fast, is super easy to use and seems to be accurate . . . the most important thing to me is that it shows zeros, and it does. I just carry it with me in my purse, and I love knowing that it's there.

Very inaccurate. Every blow was different, people who had little blew high, people who had lots blew little, very much don't recommend.

I love the portability and the price. When I follow the instructions this works just as it should. Like any breathalyzer, for most accurate results, you need to wait 15-20 minutes after your last drink (some people complain about having to wait to test, but that's how our body works). It makes a great gift too!

Definitely smaller than I thought. Which can be a good thing. I just keep it in my car. However, I have to say it always says I’m double the limit. Anytime I drink. I Uber everywhere. So this is just a fun little toy to use while out w friends. There was one time I used it and had only had a couple drinks, and it still said I was over the limit. .09 -Honestly, there’s no way to actually check the accuracy. So it could be correct! I have no way to tell. When I’m not drinking it does say 0.0. So not sure how accurate it truly is.

It does work. I was having the issue with every reading being 0.0. If you read the instructions, blow after the timer. Five seconds of blowing will give you a reading that seems fairly accurate. After I did this it fixed my problem. Directly after a drink I blow a .20 but after the 20 minute wait between drinks, you get a much more accurate reading. .10 was after 4 straight glasses of whiskey and I would say that’s spot on. I gave this 3/5 stars because of how difficult it was to figure out. Had I not fished the instructions out of the trash, I never would have figured out the problem.
