BACtrack Keychain Breathalyzer (Black) | Ultra-Portable Pocket Keyring Alcohol Tester for Personal Use

This is a great product. I purchased this after I was pulled over after an evening with my family. I had had a couple of drinks over a 5 hour period of time. A state trooper pulled me over and I was given a sobriety test and a breathalyzer. I passed all of but the way the trooper made me feel and the possibility it could have been in a life changing situation made me order one of these as a reminder for all of my adult children and myself to think twice and this can provide a moment of focused thought to help guide a decision. Way to easy to think a couple drinks are ok, all depends on the time that passes, not so much how you think or feel and the damage will linger forever.
