Bought this fan about 2 yrs ago. Beautiful looks and design. But gives a hum at medium and fast speeds and that is irritating in the room as well as the bed room just above. Air displacement also is not the greatest. I had a 52 inch Hunter fan at the same place for about 20 yrs, and was doing an excellent job with air displacement and no hum at all. I gave 3 stars just for looks. If you are noise sensitive like me, you may want to think twice before buying this fan.
