We received this item sooner than expected. It is easier to have two people to hold and screw it in place. The buttons require only a soft touch for the power/fan to start working. No cooking odors with the fan on anywhere in the house. (If you forget to turn the fan on while  you were frying onions/fish, and garlic for 30 minutes, there would be an odor accumulating in the hall/living room. But once the fan starts working, the odor fades away.) So far we are very happy with it. It is powerful, loud, but not annoying. The sound is pleasant. Has a few settings for lights with a bright option. What sold us on this product is a 2 year company warranty. Looking forward to auto clean.
