You shouldn’t, under any circumstances, drive while drunk. Again, please don’t drink and drive – we couldn’t stress on that further. This device will come in handy if and when you do consume alcohol and had to drive. Looking much like your car alarm’s key fob, it’s very easy to use. Just press the power button and blow across the grill on top. When the green LED lights up, then your blood-alcohol content is 0.05%. Should the yellow or red LED energize, then ask another person to drive for you, or take a walk home. The tester, with its built-in flashlight, will light up your way. Please be responsible, lives depend on your ability to drive. ~$11.
