Need a fast, discreet way to determine when you've had too much to drink or put a number on all of your inebriated muscle flexing? Quickly estimate your blood alcohol content (BAC) with the small and affordable BACtrack Keychain Breathalyzer. The BACtrack keychain is small enough to keep in your pocket, and accurate enough to keep your keys there as well, if necessary. The folding mouthpiece pulls out during testing and slides back down during storage. As one of the smallest, sleekest breathalyzers on the market – it also delivers reliable blood alcohol estimates in just five seconds.


We all love to go out to dinner with friends, have some drinks and laugh the night away. But when it’s time to go home, how can you be sure you're safe? Don't take that risk. A DUI can cost tens of thousands of dollars and have long lasting consequences on your career, your reputation, and even on your personal life. Stay in control and make more informed decisions with a BACtrack Keychain Breathalyzer. It's not just a fancy way for college kids to one-up their friends - monitoring your BAC is one of the best ways to maintain a responsible, healthy lifestyle. BACtrack and StackSocial don’t condone drinking and driving, ever - but we can proudly stand behind a device that educates people and enables them to make safer, more informed decisions. TOP FEATURES

“I enthusiastically support BACtrack Breathalyzers and their mission to get a breathalyzer in the hands of everyone. I know lives and families can be saved through the use of personal breathalyzers.” - Dr. Phil - TV Personality, Author, Psychologist "Even if you don't feel buzzed, seeing the numbers gives you a certain awareness you can't deny. Maybe it can make it a little easier to wake your partner after midnight for a ride or perhaps for you to part with a fifty for the cabdriver." - Elise Oberliesen - Los Angeles Times
