Title: A Blast at the Bar.. and It Keeps You from Behind Bars
Review: This product works, and it works well. It provides hours of entertainment at the bar, and, if you heed its numbers, keeps you from behind both the wheel of a car and the bars of a jail cell. Use it for fun and to save your bacon! Worth every penny, as a DUI or DWI will cost you a lot more!And as for the calibration issues. Recalibrate it by blowing compressed air through it or putting the mouthpiece out the window of your car on the freeway, mouthpiece forward, while it does its countdown. The blast of air during the countdown recalibrates the machine. Mine has worked, doing regular recalibrations, for nearly six months now.
