The Sonic Bomb Clock has an adjustable volume alarm with a maximum loudness of 113 decibels (just for reference, a jackhammer is about 100 decibels!) and the bed shaker does just that. Slip it under your mattress and your ears will bleed and your bed will shake, and there is no way you will oversleep.
