The next time you are out partying with your friends and think that you’re fine to drive home, make sure with your own personal alcohol breath tester from EFO. Blow into it and it will show your BAC level within 20 seconds. It has a built-in LED flashlight too. The price is only $11.50, which is nothing compared to the price of getting a DUI or hurting someone if you drink and drive.
