I don't know if it would work. I listen to music when I sleep, and I can sleep through noise easily. The best thing that this product could do to wake me up would be to hover over my head and land on me when it runs out of batteries.
I'd probably freak out and smash the thing to bits once I manage to catch it. Not a bad idea, though.
I'd just ignore it I ignore my alarm as it is. I also don't care about tiny little flies in my room, i'd just hide under the quilt if that damn thing went off. Nice idea, but some people such as myself are just too damn lazy for it to actualy work
I go to sleep listening to rock music, my scanner tuned on the fire dept. and the volume up, and it doesn't affect me the least.
