For only twenty bucks the BacTrack Keychain breathalyzer quickly estimates the alcohol content present in users' bodies with its accurate advanced semiconductor sensor.
After turning this sleek little device on with just one click,
users pop out the stowable mouthpiece.
The analyzer reads a single
five-second breath launched into the mouthpiece, and three additional
mouthpieces allow the device to be shared among friends or fellow parade
The keychain requires one AAA battery, which can last
through a minimum of 50 breath tests.
