    This looked cool to have. I bought it with mostly points and love it. Not exactly sure if the readings are accurate, but it’s very easy to use.

    Wow. It really measures it accurately. Just don’t do the test immediately after you drink, try it after 10 minutes of drinking

    Seems to be fairly accurate. Although doing multiple tests in a row gets different results, they are fairly close and consistent.

    Fire Hazard!!!

    I've bought two of these and they both have the same issue now after 3-6 months of owning them. They drain a battery completely dead in about 5 minutes and get so hot that I've had my leg physically burned by the unit. Not only do they pose a fire and burn hazard, but, as with all breathalyzers, the more you use them the less accurate they become. There are times where I know I'm under .08 because I only drank 1 24oz 12% drink 6 hours ago but it would read over .08... I still have both of my malfunctioning units, I think I'm going to make some videos on them to spread awareness for the dangers of owning one of these. Drink responsibly and don't burn down your house with one of these.

    It didn’t seem like it’d be accurate. We tried it a few times separate occasions at one point it read 0.0. I also read that after a few months or depending how often you use it, it has to be sent in for calibration.
