Product review (4 stars): I am happy with the unit now that it's installed
I am happy with the unit now that it's installed.  For the price it is very stylish and seems to work fine.  Installation was a lot harder than it should have been.  I was replacing an existing hood and I did few things different when installing this unit.  The duct/vent flap that come with the hood was suppose to be attached to the top with 2 screws.  This left a gap between the hood and the duct/vent flap.  I took the fan out and installed the duct /flap thing with the flange on the inside of the hood.  Also this dust/vent flap didn't mate INTO the existing duct work, it was the same size meaning it was suppose to butt exactly against it.  The problem is the duct/flap unit was twice as long as the old one.  To make it fit flush against the cabinets, I had to make the flip/duct fit inside my existing duct work, which is better anyway.  Hope this helps.
