Product review (4 stars): A good concept
I've had this for a couple of years now...it works, but don't expect a windstorm. The circulation across a 30 foot living room is improved, but I recently bought a second, smaller heat powered fan. The price is way too high...anything around the $100 range will pay for itself, but this is almost double that!  Beware getting a wood stove model...check the turn-on temperature that is listed for the fan, and first buy an oven thermometer...just flatten out the aluminum feet, if so equipped, so that the dial lies flat  on the top of your gas stove.
