Pros: First, I bought one of these motors for testing to replace one of seven 10amp fan motors in my warehouse. The result was very impressive because this motor was only using 2.5 amp running, in comparison to 10 amps with the previous motors. After about three months testing, I bought six more of these same motors to replace the other 10 amp motors. It is now two years with 10 hours per day running since they were purchased, and all the motors are still working perfectly without any problem. My light bill has been reduced drastically because of these motors. The replacement of these motors was a part of my energy reduction project to replace all inefficient equipment in the building, including changing all A/C units to inverter type, and all the fluorescent tubes to LED.
I highly recommend these motors because of their low power consumption and durability.
Cons: None so far.
