BACtrack 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.

Useful at Parties

The breathalyzer comes with three reusable mouthpieces, so you can share your gadget with friends without worrying about germs. This can come in handy in large group situations such as tailgates and parties.

Seems to get a lot of the same readings (0.14) so I am unsure as to its range versus the subject physiology. For $25 bucks it is a useful starting point.

Too early to tell, but so far so good. For those who have the interlock, this is the way to go. I suggest not getting the insurance due to the cost of calibration. It seems cheaper just to buy another one.

Didn’t work. My 12-year-old blew in it and it said he had a .02, I had one glass of wine and I had a .14! Not accurate
