Sonic Alert SBP100 Sonic Boom Portable Vibrating Alarm Clock

Rating : - Wakes up heavy sleeper
I bought this for my son who was oversleeping and missing classes. He told me the vibration really does the job waking him up. The fact that it doesn't need to be plugged in and can go anywhere is a plus. It is much smaller than I thought but this makes it great for use as a travel alarm.
