    Well worth the expense. It’s better to be safe than sorry. Good to have when you go out and have a couple drinks. It lets you know if your within the legal limit of intoxication. And I’d rather pay $20 than $10,000 for a DUI.

    I have owned 2. First worked great for a year and a half and then I stepped on it. I bought a second, and the calibration was off (after drinking 4 or 5 beers i was still legal to drive... no way possible). I returned to best buy, they exchanged for another, which again works perfectly!

    Works well and helps a lot--convinces me not to drive even if I think I'm ok. Of course when you've consumed alcohol you really are unaware of the true reaction time. We all think we are ok to drive. I ALWAYS listen to this machine. THANKS

    I've only used this a couple times. Last week I had a six jello shots and after 40 minutes my BAC was 0.0. Then had five beers over 2 hours and my BAC was .0815. Stopped drinking and drank about half a Powerade and my BAC only dropped to .0805 after 90 minutes. Forty five minutes later it was .0515, but I didn't drink anything. The previous week I had four beers, but I didn't wait the 15 minutes you're supposed to and my BAC was .0515. Not sure how accurate this thing is.

    I gave it four stars because the only issue I seem to have is that data does not show up all of the time on multiple smart phones linked to the same account.

    Not sure how accurate it really is but it's a good baseline and seems fairly consistent. Fun to try and blow higher than a friend at a party

    As a older middle-aged person who never had alcoholic beverages before and not knowing how I would be affected, this gives peace of mind when my wife and I go out and have a drink.

    It's interesting to see your blood alcohol level. Really nice product for the price. I don't really have a main point of buying it but it's nice to have
