Summary: I installed this fan in my garage since it would vent towards the side of my house (and my neighbors) and noise was a paramount issue. Though not totally silent outside (likely due to the air passing through the rigid duct) it is super quiet inside.
Pros: Easy To Install, Powerful, Quiet, Sleek Design
Summary: Very quiet fan. Fan requires a larger hole in the ceiling than a standard bathroom fan - so requires some planning and effort during installation. Fan has greatly improved humidity problem in our bathroom.
