Product review (4 stars): Works very well and fits bracket, clears the air quickly.
4 stars as I have not had it long enough to evaluate longevity of the motor.
Fits well and works well,  as  others have mentioned it is somewhat loud.
But for the price and seeming quality would buy again.
Keep in mind this is a fairly powerful motor and it takes the humidity and fumes out of the bathroom very quickly.
Fits perfectly in the holder bracket and changing the plastic fan over was just a matter of taking the locking nut off and transfering it to the stem of the motor.
