Negative Positive
Title: Extremely loud
Review: This fan is extremely loud. In heating mode is even louder. The fan blade must be out of balance, because when running it creates vibrations felt one floor above. I made same mistake again buying this brand fan when remodeling older bathroom. The other Broan/Nutone (same company) runs exactly same: very loud with vibrations. Cheap small fan blade spinning very fast inside. If you can spend more money, go with Panasonic. I purchased 6 fans in different sizes for new house and they all run perfect, almost hard to hear when running. Panasonic uses very large turbine spinning much slower, perfectly balanced, very quiet, no vibrations.
Is the review positive or negative?
