This device is great. Not only is it easy to carry around, it's an affordable price, it's easy to use, and can show you that solid number indicating your impairment. Everyone has had a social evening of drinking in the past, but sometimes it can be hard to tell how impaired you actually are. This device takes away the "guessing" of whether you're okay to drive.
I would recommend this to a friend!
