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.

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

This is a must have if you are going to go out and have a couple of drinks then get behind the wheel. I always wanted to know what my BAC would be if I had 2 glasses of wine, now I know. It's surprising how little it takes to get you to or over the legal limit. My husband is usually my designated driver but if he's not around and I want to go out with the girls and I have to drive myself I will always have my little 'friend' with me.
