You can never too safe when it comes to driving. My friend Sean bought one months ago and it was the best purchase. It's important to be sure of your alcohol level especially since cops have been cracking down hard. I'd rather test it each time than risks a DUI or my life driving

This is a very good device for the price, it appears to be very precise and it can come in very handy because you will probably find yourself in a situation where you have to drive after a drink. I wouldn't use it as a keychain though because it can get banged up.

Your kid won't drink much at college? Get them a breathalyzer just in case which they might find fun at parties and they will split Uber or Lyfte rides with friends instead of risking driving drunk or buzzed which is also drunk. My daughter bought one for her friend for her birthday...and she is a true friend. This brand & model shows more info than some others.

This is our second unit as the first broke about 6 months after purchase. The back had to be taped shut within 3 weeks of purchases. While its overall use is to effectively determine if someone is legally drunk it has become a part of many adult weekend drinking parties.
