From runaway robots to "sonic bombs," we reviewed offbeat alarm clocks designed to awaken even the heaviest sleepers. Not every alarm clock is created equal. Heavy sleepers know how easy it is to snooze through the overly genteel alarms on your phone. For people who can't get out of bed without a bigger jolt, extreme alarms have popped up in recent years--from relatively simple puzzle-alarm phone apps to alarms on wheels to alarms that shake the bed. Not only are these an innovative way to get chronic snoozers out of bed, but they can be great for those who are hard of hearing, utilizing different frequencies and pitches as well as movement through vibration.
