Up until now, hot flashes from menopause have been disrupting my sleep for weeks. My only way to cope has been to crank the thermostat down to 70 degrees at night (wasting energy to cool the entire house), and set up a fan next to the bed to blow directly on me. Even so, I'd wake up several times a night, fling off the covers, cool off, then get too cold, and pull the covers back over my head. The annoyance and sleep deprivation made me desperate enough to spend $80 on a solution, and I'm glad I did.
The Bed Fan took me about 5 minutes to set up, and worked great from the very start. I started out with the unit turned to a medium-intensity setting, and soon discovered that I could turn it down to a very low setting and stay plenty cool. The fan is blissfully quiet compared to the room fan I'd been using, and I appreciate not having to supercool the bedroom. There's enough clearance under the top sheet (where the fan frame holds up the sheet at the foot of the bed) to allow me to turn over, move around, get in and out of bed without the sheet coming undone. The only reason I'm giving it 4 stars instead of 5 is that it does seem rather overpriced, especially given the less-than-substantial feel of the plastic.
