Product review (5 stars): Operates great.
The manual I received had printing on every other page, but downloaded the full manual from Broan with no problem.  Installation was spot on with the instructions.  I made one modification which helps.  When the fan is on at full speed, the exhaust flap didn't fall back closed as it was supposed to.  I ended up wedging a spare piece of aluminum in there and bent to act as a movement limiter which would allow the flap to fall closed as it should when the fan is shut off.
