“Bought this as a tool to help friends realize they were over the limit, took my BAC once out of the package and it read 0.00 (correct). Drank a few beers and mixed drinks with friends, waited 20 minutes between drinks or smoking and got 4 different readings within 5 minutes ranging from .01-.21.
Not worth the money.”
“I bought this Breathalyzer not too long ago and it has really come in handy. It was a little confusing at first but easy once I got the hang of it. I use it all the time! Its small and so convenient to carry around.”
“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.”
