Keychain Digital Breathalyzer Alcohol Tester

This compact keychain breathalyzer lets you check your blood alcohol content quickly and conveniently, right from your keyring. With an audible alert and fast response time, it gives you an instant reading so you can make smarter decisions before getting behind the wheel.
