Nothing I can complain about. I just wished I purchased something more powerful for my application.
I beat up this motor, held it still while trying step, and turning it while it was trying to hold, but no complaints per the motor. I got it stupid hot in an attempt to really work it, and it still responds quite well. So I only have good recommendations for this motor.
(I'm going to order the 84oz motors for my application, and use the same seller :D )

Great quality stepper motors

Very impressed. Performs Much Better. The Motor is a Beast.
This motor is a beast. Using it on my Wanhao DI3. With a Flexion HT extruder. With the torque that this motor provides, i am able to tighten the jam nut much tighter than what i would before. Print quality and torque are very noticeable. Had to adjust stepper driver for 1.44v. The motor is a beast.
