I love this product. It's so simple and easy to use. Worth every penny. It's a very nice asset for anyone who is a social drinker who wants to be responsible. I would highly recommend this to anyone.
I just received my keychain today. I put the battery it came with into it and tried it out. It seemed to work just fine. But when I went to try it out tonight, it wouldn't even turn on. I changed the battery to a brand new battery and I still cannot get it to turn on. This product does not work at all.
Bought this a couple months ago. The only reading I ever get is "FL", over and over. I was actually very excited about using with my friends. Disappointed about it being a dud :(
I've had this for about a month now. I use it to pre-test prior to blowing in my breathalyzer in my car. Since purchasing this I have not had any violations!! It has been very accurate.
I just bought one for my college daughter and for myself. It's the best way to make sure I should legally drive after having a drink at lunch or dinner.
I purchased this to see if I could safely drive my vehicle and decided to test it out. After having 3 beers (7%, 8%, 10% abv) over a 2 hour period I blew a 0.04. There is no possible way that it was that low after consuming 3 high gravity craft beers and I was pretty intoxicated.
