It's as quiet as all the competitors and sounds the same as any squirrel cage fan. Nice digital readout. The lights could be brighter, but they'll work. There are no logos printed on the exterior of the fan, I like that. Except for drilling a 6" hole through my exterior wall it was an easy install. It came well packed.  I wish the gasket for the vent adapter would have been packed flat, otherwise I give it 5 stars! Nice sleek design.
