This is useless as a vent hood because even on the lowest setting it is incredibly loud. I had the appliance store and builder listen and they just shrugged their shoulders. It's too bad because it looks nice. The appliance store had me listen to other brands on display in its showroom. None of them was as loud on its highest setting as this one is on it's lowest. Very disappointing. How can they sell this when so many reviews complain about the same thing.
