First, this hood should have a better photo that clearly shows how rounded it is at the top. This wouldn't have changed my decision to order it, but it might for someone else.
Second, the installation method was awful; there's no other word for it. The backplate provided was not wide enough to reach even one stud, keyholes do not work for a range that sits flush up under a cabinet (there's no room to slide) and the instructions claimed that we would need only the backplate OR to drill up through the hood. This resulted in my husband holding up a 60 pound hood while I attached the backplate (to solid wood that I had run between the studs) and then for about 20 minutes after that while I figured out how to get it actually secure. There were no actual pilot holes, and I was drilling from above (the underneath is too tight to get a drill in), so I had to just attempt to aim for the drawn-on hole placements so I could screw a nut in underneath. Truly one of the worst installation experiences I've had.
My four star rating is because now that it's hung, it feels like a good quality appliance and does a great job clearing the smoke, vastly better than our old over-the-range microwave.
