This 120 dB door stop alarm could be good for traveling I guess, but if all the mean-spirited friends and family members I know figured out I was using one to protect my bedroom from their snooping eyes and fingers, I can guarantee someone would trip it at least twice a week, and probably multiple times on weekends, just to be a jackass who shatters the peaceful slumber of an angel who cannot function without 10 to 14 hours of sleep per night. The alarm has an adjustable sensitivity switch so that the cat or my mama, who is always polite and knocks...albeit a little too forcefully for my tastes...won't set it off.

Josh Renouf knows what the world really needs: coffee. Stat. Like, the second it opens its eyes. And it needs it served from The Barisieur, an alarm clock topped with implements from Beaker's lab. Very nice, Mr. Renouf....
