This jarring alarm clock uses high-decibel sound, flashing light, and a bed-shaking vibration pad to wake even the soundest of sleepers. About as loud as an idling bulldozer, the 85dB alarm prevents the most stubborn dozers from extending their slumber. The alarm clock connects to a lamp and automatically turns the light on and off in tandem with the alarm. A vibrating pad can be placed under a mattress or pillow and provides an insistent, bed-shaking tremor that serves as the last line of defense against oversleeping. The clock has an easy-to-read LCD and snooze button. Requires one 9-volt battery for power-loss backup. Plugs into AC. 4" H x 7 1/2" W x 2" D. (2 1/2 lbs.)
