Product review (4 stars): Looks great, works fine.
Louder than I had hoped -- but I think that's because the installer put in a reducer at the top of the duct.  However, it works great, and looks just amazing.  I would recommend.

Update:  After a couple of months, I had the installer come back and remove the reducer and re-work the roof vent.  That made a HUGE difference in both the loudness and the performance.  I love this hood!  Not only how it looks, but how it works, too!  Only 1 issue -- the clock doesn't keep time. It loses a minute every few days.  But since I keep the power off most of the time, I don't see the clock much, so it's not a big deal for me -- but drives my sister bonkers every time she comes over... another reason to love it. :)

Update after nearly 4 years: Still works great!  Easy to keep clean, and looks great.
