Product review (4 stars): Sleek and clean.
Great piece of hardware. The biggest issue we had with it was that the sleeve that covers the vent is next to impossible to slide apart. It took two people and a lot of time to slide it apart, then it took a lot longer to adjust it to just the right distance apart to fit right. Now that it is up and I don't have to adjust it anymore I am in love.

-Pros
Great fan
Easy to clean vents
Great adjustable lights

-Cons
That stupid vent sleeve.
