Drive Alert Master
Just turn it on, adjust the wake up angle switch and place it behind your ear. When you begin to doze off and your head slumps forward the Drive Alert will emit a LOUD, powerful BEEPING sound to wake you up. Using the Drive Alert could save the lives of you and your loved ones. And it may be the best safety device your car never had.
This will keep awake during those long drives. when you start to fall asleep and your head slumps and loud noise alarms.
