Product review (5 stars): This is a great unit and you will not be disappointed.
Great unit, It is incredibly quiet.  It works well.  The install was a breeze and I loved that I could vent it in two different directions.  If I had to do it all over again I would order another unit.  My only advice is know that this goes from a 4x10 exhaust, if you have a round vent in the wall already you will want to buy and adapter as well to fit your pipe.  Adapters are less than $15 and are universal, you can buy them from amazon or local hardware stores.
