Product review (3 stars): Moves a lot of air, not very quietly with light issues.
I have mixed feelings. It definitely moves a lot of air, but it's a little noisier than I had hoped for, I thought I was buying the quiet model. I found having a less restrictive top on the vent above the roof helps somewhat. My biggest problem is the halogen lamps, one of them when out within two months and they are extremely difficult to replace. The thin metal bezel requires a poorly designed special tool.  The light fixture does not accommodate some LED bulbs with a tapered face.
