Title: DON'T WASTE YOUR MONEY ON IT!!!
Review: I'll leave a very short review -- don't waste your money on this cheap breathalyzer! I bought one thinking I'd save but in a long run I lost, because it is so inacurate that it becomes a joke. The reading greatly depends on how far your lips are from that hole that you need to blow in. Here's an example: first time I blew 0.9, a couple seconds later it became 1.7 and the third time it was 0.6. I cannot imagine anyone trusting this kind of reading. I think I'm going to invest into a little bit more expensive model.
