Had to purchase 10 (six 52” and four 48”) of these to get 3 to work ... company claims high quality and fans that don’t wobble on their website but all of mine wobbled.  The metal plates attached to the motor where either warped or misaligned.  Spending 45 minutes hanging not one, not two but NINE fans that wobble is not only frustrating but time consuming.  Many times I asked if maybe production put out a bad LOT but no one seemed to want to take the time to reach out and discuss the issues.  Waiting on the next shipment of replacements ... if these don’t work I give up.
