Product review (1 stars): Awful Design
The instructions for installation are not correct for this item, the manual is only good for fan and timer controls. I had read other reviews saying the install was a challenge, but ordered with confidence because my husband is an extremely skilled craftsman and he can build anything. After reviewing the parts and the assembly, he determined that like others had said, the item cannot be installed as directed. He made a trip to the hardware store and had to cut some pieces, drill new holes in the metal and weld on supports, but has managed to install the range hood. I will say that the hood is quiet and the motor is strong, but unless you have a degree in mechanical engineering and the help of a machinist, DO NOT BUY.

I cannot stress this enough, you will regret this purchase.
