Product review (3 stars): Good duct, hard time hooking it up...see review.
It;s a vent hood, does what it should.  The slot for the sheet metal duct to go in is a royal pain to get the sheet metal in.  I have arthritis, so I won't beat them up on this too much, as lots of things that used to be easy for me to accomplish are now really hard.  If it weren't for struggling with the duct attachment I would give it 5 stars.
