Bests & Worsts Reviews from Amazon

Well, I have seen lot of those come and go over years, this one is no different. I have changed lots of those. I took this motor apart to see if anything has changed, NONE at all. Failure is bound to happen in A season or 2 because there is no real ball bearing on the shaft, it has bush/sleeve (High Maintenance) with no lubrication ports. Per instructions came with the fan says lubricate often (With non detergent oil) but how?? Construction of the motor is same as it used to be for the last 15-20 years with some minor changes but shaft and bearing housing assembly remains the same. It used to be $20 motor, it went up gradually over the last couple of years to $55, no matter where you buy it from Homedepot or online. I'll give it 2 stars for the reason, price is right especially it comes with thermostat. I installed mine couple of months ago, it's good. Made some mods to lubricate front & Back end of the shaft. Just a thought to share, expensive motors have low maintenance because they have permanent lubricated sealed bearings.
