I've been looking for something because I live in Arizona and can't sleep at all when its hot. My options are to run the AC non stop all night and pay a huge electricity bill or turn on the ceiling fan on and sweat like a dog.

This one seems fairly priced and has decent enough reviews that it is intriguing. Anyone ever used anything like this? Do they work at all or is it just a waste of money?
