This model is easier to install than most models. The screw holes are cut in a way that if the screws were pre-installed on the cabinet first, the hood can be lifted up and hang onto the screws, it make the installation much easier (I will give another half star if a cardboard screw holes installation template is included in the package). The suction is as good as our old hood that cost double. I took one star off because of two reasons: 1. A cheaper model from the same manufacturer included a delay off timer, this model don't. 2. The LED is too weak (3W) and at an odd angle. The outside stove is only half illuminated. It is easy to fix, I replace the LED with wide angle 6W LED but I shouldn't have to do that myself.
