I guess the idea is that it's preferable to an alarm clock, whose shrieking beeps and buzzes make for an unpleasant arousal.

I have an alarm clock/lamp that slowly increases light and audio levels (I have it set to bird sounds). It's great for a gentle wake-up, but the bird sounds get repetitive if you don't snooze/turn it off after 20 seconds or so.

My biggest issue with Napwell, aside from the obnoxious information desert that is its homepage, is that I could never fall asleep with a thing strapped to my face.
