Drive Alert Master, Wakes You Up

If your one of the millions of people with some sort of sleep deprivation and tend to nod off while driving, this is a gadget you might want to have a look at. This little gizmo looks just like a Bluetooth cellular ear bud, but has nothing to do with talking. You set an internal Sensor to sound an audible alarm if your head tilts below a preset degree limit. Plus at only $14 posers can use it to pretend they have Bluetooth on their cell phones.
