Very Effective
Cant be turned off without getting up and spinning. I tried various ways of stopping it without getting up, just to see if its possible--it isnt. The "end of the world" tone is by far the worst tone Ive heard, which means its great for actually waking up. If youre going to close your eyes even for a few seconds after spinning, do yourself a favor and set another alarm. This is excellent for people who sleep through alarms. Dont rate it poorly because you went back to sleep after; thats on you.
