Product review (3 stars): Looks ok--fits the space
I have an exhaust stack that goes up through the attic, I installed an American Aldes Spring Return Back Draft Damper - 7 Inch also purchased thru Amazon, My only complaint with the range hood is the variable speed fan vibrates loudly at many different speeds. You have to fiddle with the speed till it is at an aceptable noise level--delivery was quick as always with Amazon..
