Great price and quality. Using on a 3 axis mini mill CNC conversion. Using a sparkfun shapeko and grbl. Good repeatability and excellent holding power.

I love these motors. I currently have 4 of them and I have had them for about six months. They work great for what i was using them for and never seemed to have a problem. Just make sure you buy the right motor driver and power supply that will actually allow enough current through to power these motors. I was using drivers that had too low current output that kept it from using its full torque capability so it kept skipping steps. I have now fixed that problem and they work like a charm.
Pros:
smooth
very accurate steps
no need for radial encoder with proper set up and usage
Cons:
none
I recommend this motor to anybody that needs a strong motor for either a project or in need of some type of upgrade.

I had trouble getting the claimed torque out of the motor however it was close at 85-90% you could chalk that up to instrumentation error, I suppose.
