It moves a lot of air which is just what I was looking for. I use it daily to circulate the stale air out of the bedroom and hallway and out the window. My only disappointment was with the tilt - not sure if mine was defective but it will not stay pointed in the angle I want it, it slowly drifts back to an upward position. I'll probably wedge a rubber stopper to keep it from doing that in the future. Otherwise, great product.
