GE APPLIANCES UVW93042PSS ducted hood

The unit is really beautiful no question about it. It is heavy, sturdy, and definitely well built. My installation is top vented with 8 in duct and fixed to the back wall with the installation bar. The provided paper templates helped alot on this. There are few things that could have been better. The top damper screen holes are off by as much as 1/4 in on to the main unit. I had to drill (see photo) 2 different holes on the unit with a drill bit #2. I think the screws provided are self tapping so it was not a problem even if the holes were not exactly the same size (slightly smaller). Given the price, I wish the provided the coal filter and at least on small duct cover. Yes, i know they are quite expensive but the unit itself isn't cheap either. My recommendation, if you hired a contractor to install make sure you tell them to tape (aluminum tape) any obvious air leaks and ratling metal around the motor, the damper, and the ducts.
