Product review (5 stars): Good Hood
There are several things we love about this hood compared to most we looked at.  The dual spotlights do a great job illuminating the cooktop, and the closed bottom makes for a cleaner looking installation and will definitely be easier to clean in the future.  On the low setting the fan is so quiet my wife sometimes forgets she's turned it on, and on the high setting while it's not exactly silent it's considerably quieter than the older unit we replaced while also moving a fair amount of air.
Installation was pretty much what I expected, our only difficulty being that our kitchen cabinets don't quite have the shape the hood designers expected--and when we took the old hood down we could see that the original installers had faced the same problem with our old hood so it's not the hood that's odd but our kitchen.  We ended up adding a couple pieces of wood to fill the gaps that shouldn't have been there and then screwed the hood into place as it was designed.
