“I bought two of these keychain breathalyzers because I thought they were neat. The only time they will show an actual reading is right after you have taken a drink of something. I can drink 10 beers and still show a .00 on both of the devices. Not worth my money, but a good conversation starter at the least. I definitely would not buy one of these if you are planning on relying on it before you drive home.”
“The only thing that is annoying is the last digit is hard to determine
what number that is. By turning it a few times you can just about
read what it is. I like the product though.”
“I bought this product yesterday. I had a party last night and consumed quite a few drinks. Towards the end of the night I wanted to see how it worked. It never blew over 05. There is no way I would have got in my car after that many drinks. I'm glad I was at home and didn't have to put my trust in the keychain breathalyzer. Maybe I just have a faulty one.”
“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.”
“I bought one at Best Buy a month ago and am surprised how well it seems to work. It seems to be accurate and fun to use. Even when we use an Uber it's fun to see what your BAC is. Highly recommend!”
