The builder installed this when I insisted on a down draft cook top as I do catering. The small rubber feet fall out all of the time. Cleaning the filter area is fraught with danger as there are exposed screws that scratch me, the filter well has rusted twice. The fan assembly takes up most of the cabinet underneath. Cleaning the burners is a real chore as they are too big for my laundry tub, never mind my kitchen sink. I have been assured the whole thing was installed to spec. Don't waste your money.
