I rarely write reviews unless I have strong feelings to the good or bad. This fan is GREAT. The motor is virtually silent in all three speeds (and I have excellent hearing.) you only hear the wind sound at the high speed, not the motor. The other two speeds are quiet...perfect for sleeping. It was relatively easy to assemble and install. The only complaint is the the cheap made in China fan screws are so soft that the Phillips head strips at the head right off the bat, so I needed to use a vice grip to grip the sides to loosen the screws to attach the blades. We also switched out the main bolts holding the fan to the stud with our own lag bolts.  Even with these mild irritations, I still give it 5 stars. We have a large bedroom 15 x 17 and it works fine for that space, and that’s the biggest room I would use this in....
We will be getting one for the guest room next!
