Product review (1 stars): Cheap plastic design, fan stopped working at 7 months.  Waiting to see if a refund will be given. Pretty, but junk.
This is a piece of garbage.  Less than 7 months old and the fan blades have stopped working.  The motor just spins.  I thought it was a piece of junk crap from day one but I had it hung in the kitchen and removing it will leave a big hole in the ceiling.  Now no choice.  This thing arrived with a broken plastic flap to keep the cold air out and they did replace that.
Fair warning, if you want a good looking but cheaply made unit, this one will do the job, just so long as you don't use it.

UPDATE 11/20/2014.  I have to give Golden Vantage a good review. Upon letting them know, I told them I could fix the unit if I had the parts.  They sent a new fan/motor/housing assembly to me and it fixed the unit back to new condition.  I noticed on the old part that a simple drop of locktite probably would have prevented the lock nut from backing off on the motor shaft and that would have saved us all a lot of time, shipping parts and doing repairs.  The communication back and forth during the parts ordering was always pretty quick, most of the time less than a day. Thanks to Justin.

Based upon the price of the unit and the service that was available after 7 months later, if I ever replace the unit then I won't hesitate to go back to Golden Vantage to buy another one.
