    I know it's probably not as accurate as one a cop would have but I think at least it gives you a good idea of where you're at. Nothing is worth a DUI, and there have been times were I've been higher than I thought I would be. Would definitely recommend.

    Calibration every 6 months

    So.. didn't do much research and bought this because it seemed like it could be useful and not bad at about $30. Then I get it home and read that it needs to be recalibrated every 6 months which is a $25 fee and involves shipping to California. Wish I didn't even buy it in the first place. Also found out that the more expensive ones have to be recalibrated every year so none of these are products you can use down the line without additional costs and hassles.

    Bought to monitor someone with a drinking problem to make sure they weren’t drinking and driving or otherwise but it wasn’t always accurate and would even register myself as drinking when I had not

    I got this more as a gag for a work party. It turned out great when we were going to go to another bar, I got 3 people to leave their cars because they blew a .8 or more and thought they were ok to drive beforehand.

    Bought this for my son, guess I was trying to tell him something, he thought it was a really cool gift, a great conversation starter anyway. Since I gave it to him he has decided he needs to slow down on the beer.
