The nap zapper is an anti-drowsy alarm designed to raise
drivers awareness of momentary lapses caused by sleeping
and tireness. Wear behing the right ear, it works on the
principle of electronic balance. As the driver's head nods
below a preset angle, it emits a loud alarm signal alerting
the driver to take corrective action, take a break or even
take a nap.

The nap zapper is not only designed for drivers, it is
perfect for people who need to be on full alert while on
duty such as security guards, machine operators, and even
students who need to work on their posture.
