4" Flat Whisper Fan - 100CFM

I ordered two fans and received them a couple of days ahead of the anticipated arrival. One of them had a small piece of the frame break somewhere along the line, as all boxes were intact. However, I super glued it back together and it works just as well as the other one.Both fans are super quiet in my installation. Compared to a bathroom exhaust fan, which pushes less air, it is whisper quiet.All in all, well worth the money. The arrival was better than quick and the little bit of damage was no problem to fix. It didn't affect the performance before or after it was fixed. Or my choice to go elsewhere to get more. Amazon rocks!

I purchased two "whisper fans" which proved too loud for my use. I wrote Amazon twice about returning them, and got no reply. Finally I directly contacted the seller, who grudgingly offered to give me credit for the fans, but not for the significant cost of sending or returning them! This is, I believe, contrary to Amazon's stated policy. But Amazon has never replied to me. I only recommend this fan for noisy environments, and I am disappointed in Amazon.

I ordered 2 and was very pleased. Exactly what I needed. Relatively quiet. Mounting holes perfect size. No problem whatsoever. The price was good and I got a discount on the shipping for the second one.
