Product review (5 stars): Great stuff, and can install it yourself.
I ordered this to replace the old one. This is a great stuff. It's not too hard to install. It took me 3 hours with some help from my wife. I installed it under cabinet. Inside the cabinet, I put a wood stud on each side, and screwed 4 of 3" nails from the hood underneath. It is a top hanging installation. The important part is placing a hardboard with smooth surface under the range hood and putting a long 2"x2" wood stud under the board very tightly to support it from the floor. Now you can adjust the position, center the hood easily. Please pay attention to the stud, it should be really tight and in the center of the board and align to the center of the hood, not slip on the floor. Better have your wife hold it and monitor for you. Safety first always. The way I installed it is for reference only and not responsible for any fault. If someone needs a picture to see how I placed the hardboard and stud underneath hood for installation, comment here so I will post a picture.
