Product review (4 stars): great product almost...
I love having a fan that is ducted to the outside.  It's great.  The noise level is decent too.  I only have the old microwave fan I used to have to compare and this is much quieter.  Makes cooking much better.  The only thing that I would change is the button design for on off.  I have to reach up inside my hood to turn it on and look for the small black switch to slide amongst the black background.  An easier to see or feel toggle might have been better.  Especially for the light.  If the buttons were better, I would give this a 5 star rating in an instant.
