iPod Alarm Clock Bed Shaker Won't Work for Me

This is the iLuv iMM153 Desktop Dual Alarm Clock for iPod, which has a bed shaker that is supposed to wake you up better than any alarm. Obviously, these guys haven't tried this thing with me yet.

Like any other alarm clock with dock—compatible with iPod touch 2nd generation, iPod nano 1st to 4th generation, iPod touch, iPod classic, iPod with video and iPod 4th generation—the iLuv iMM153 has built-in speakers and FM radio. Unlike other alarm clocks, however, the iMM153 comes with a small unit that will vibrate to wake you up. At $59.99, it doesn't look bad, but I will need to daisy-chain a few of those if I really want them to wake me up. [iLuv]
