This product is supposed to be a "quiet" model yet there is "hum" or "buzz" (probably the transformer for variable speed fan) underlying the fan noise regardless of what speed the fan is adjusted to.Worst POS ever. This is the second one I purchased. When we remodeled the kitchen we put the tile all the way up to the exhaust fan. The first time after about 3 months it started making this horriable rubbing and screeching noise. So we went and bought another one. Samething happened again. Horriable rumbling and screetching noises. Worst fan ever! The crapie manufacturing make it work like crap. Hate that we bought 2. So save your money and stay clear of this one. They sell them at homedepot and will not buy another product from Broan again!
