Everyone of us has experienced drowsiness while driving.
Some of us have actually fallen asleep only to be awakened
by the blaring horn of an oncoming car.
Avoid this potential tragedy by wearing the
Nap Zapper on your ear. If your head should
nod, an alarm will go off, waking you and any sleeping
passengers in the vehicle.
Uses one 6 volt alkaline battery (included).
