This Nap Alarm will help you keep awake when you are driving, if you are tired, feeling drowsy, for long-distance driving or night driving.
The alarm is placed over your ear, and it has an electronic position sensor, so when your head nods, it will sound a loud alarm to instantly wake you up, or alert your passengers.
The nap alarm is also nice for other situations where you need to be awake or fully alert when you are on duty.
It uses 3 AG13 alkaline button cell batteries (included).
