We've had these fans (2) for 3 months now and they work great.  They're very quiet and were easy to put together and install - even for us who are not super handy.  You do need a 2nd. person to help hold stuff up while you screw it in.  I like the fact that they are flushed with the ceiling, so we have more space to move under them.  Both fans are in bedrooms and the move the air quite well.  I would buy them again if we need to change the fans in the other bedrooms.  Great price!
