Personal breath tester! Are you ok to drive? This breathalyzer will tell you when your ok to drive or not. It measures your alcohol content, so no more guessing if you can drive or maybe call an uber to get you home. It sells for $70 at Walgreens, and yes it is very accurate! Ive tried and tested it. Cash only, pick up only! IF YOU TEXT ME AND ASK ME TO EMAIL YOU BACK, NO!
