“I am involved in a collegiate sport so I maybe drink once every couple weeks but when I do, I go hard.This is a fun gadget to use to show off to friends just to see how drunk everyone really is. That being said, it is way too easy to skew the results. You have to wait 1 minute between tests in addition to having not smoked, eaten or drank ANYTHING for the 20 minutes prior to the test.Obviously, a drunk person is almost incapable of doing any of this. A friend of mine (6'8" 220 lbs) blew a .22 after only a few beers because he didn't wait long enough to test. Either way, when you follow the rules it seems to be accurate although I've never tried to confirm reading with a second test. As with any civilian breathalyzer, the point is pretty much for it to be a toy/gimmick anyway. The instructions say that you'll need to get it calibrated every 6 months potentially which costs you significant money and with the unrealistic 20 minute no-ingestion rule, this product seems to be asking to get broken. Bottom Line, it seems like a money pit that I'm glad I got as a gift from my sister and didn't actually spend any money on.”
“I saw one of these at a Christmas party. I won with a .17. My synical friend said that didn't make me a winner, but I wanted one anyways. Accurate enough that if you blow over the legal limit; you shouldn't drive. Had it for 3 months and it still works good.”
“I carry this every weekend when I plan to drink so I can check my BAC before I plan to drink. I already got a DUI a few years ago and don't plan to get another one as long as I have this as my helper.”
“Had fun using it at the Super Bowl party. I can't say how accurate it is, but one very drunk person blew very high and I only had two glasses of wine and blew below the legal limit. So I assume it's somewhat accurate. The beeper could be a little louder because no one could hear when it was time to blow. And this was just in a regular house setting - not a noisy bar. So, you just have to do as the instructions say and get ready to blow at "2". I like it and continue to carry it on my key chain. Would recommend.”
