Keychain Breathalyzer

Track Your Intoxication

After just five seconds of blowing, this keychain-sized breathalyzer can estimate your blood alcohol content.

Clean Test Samples

The breathalyzer’s mouthpiece is designed to capture your breath and your breath alone. That way, contaminants in the air around you, such as fumes, airborne gases, and mundane conversations, don’t taint your reading.

Said I was drunk when I had nothing to drink, said I was sober after having several drinks. Do not recommend.

Gave it to my college son (president of his fraternity). He would have all the frat brothers test before any could drive and even used it for the designated drivers!

They're cool at first, but they get uncalibrated really easily.

It gives false readings. I drank a glass of wine and then blew in it and it showed 0.00% The next day I didn't drink any alcohol and I blew and it said I was .04%. Its awful. Very unhappy.

This product is junk, it doesn't work and the we had to use two batteries for the first night. It's not worth the $20.
