I love this fan but it is almost too powerful as quite mode is not that quite. Yet top speed is quick to clear air. Note, I did reduce the duct work to 2 x10 so that could cause a bit more noise. Top mount or rear mounted exhaust duct is great. ￼I used top mount which allowed me to set the unit further under cabinet to give me more room so I don’t knock my head into it. Lights are nice and bright.
