Product review (1 stars): DOESN'T WORK!! It just pushes smoke into the kitchen.
Poor design. My kitchen gets really Smokey and this just moves it around. The hood itself is shallow and does not capture smoke. The hood has gaps in the sides. The plastic accent piece bows out and smoke escapes through and is pushed into the kitchen. There is a rectangular plastic piece that falls out where a carbon filter can be placed if you don't have an exhaust but it does not seal.  This is an embarringly terrible unit for the manufacturers and I would return it if it wasn't already installed professionally. You get what you pay for. My Nutone was much better even if it was 40 years old. I guess you get what you pay for.
I had to duct tape or glue the entire black strip to stop the smoke, now it looks really trashy. See pics.
