Everyone has experienced drowsiness while driving. It's a scary feeling to be half asleep while driving and to be woken up by the horn of an oncoming car. The US National Highway Traffic Safety Administration estimates that approximately 100,000 police-reported crashes annually (about 1.5% of all crashes) involve drowsiness/fatigue as a principal casual factor. Now you can fight that feeling with the Nap Zapper, a small electronic alarm that fits easily and comfortably behind your ear. Emits alarm when head bobs if you should fall asleep while driving. All Truckers, Bus Drivers, Taxi Drivers, Limo Drvers, and long distance drivers should have one of these. Makes Great gifts for the ones you love. $10.95 could save their life!
