This could work for me. I'm in the same camp as the second poster, my alarm clock is on the other side of the room, and I also have my cellphone which doubles as an alarm clock beside my bed. On a number of occasions, I have slept right through as many as 5 alarms, including sleepwalking through the 2 alarms that the clock on the other side of the room produces.
This device may work for me, as I would be able to turn it off while on sleep-induced autopilot.
