Product review (4 stars): Final Verdict-Great Product in Spite of a Few Hiccups
It works wonderfully, but was a real chore to install.  Duct work match up caused the most problems.  I had to retro-fit the duct and the Broan adapter to get a good seal between the two. Also, the fan on low is virtually silent, hard to tell it's running.  On the other hand the high speed is noisier than I expected, but not too big a deal, since it runs in the kitchen and is on only as long as needed.  Looks great in our kitchen.

One other thing.  This was the third Broan we received over the period of about six weeks.  The first two arrived unusably damaged.  From the looks of both boxes, which were in perfect shape, the dents occurred prior to packaging.
