CNET reviewed Q3’s AlcoHAWK Slim Ultra! This is a little battery-operated breathalyzer that immediately shows the alcohol level in your bloodstream. The device has just one button and a little round LCD screen. Press the button and blow into the mouthpiece, and after a few seconds, the LCD will show your blood alcohol concentration (BAC) on a scale from 0 percent to 0.40 percent.

With the 4th of July right around the corner, this might be a handy little device to make sure that you and your friends have a safe holiday weekend.
