I was surprised to see such a great stepper for such a low price so I decided to buy one and see how well built it is. Well I've since bought two more and plan to use them in a CNC router/mill. They're pretty well done. I think my only real complaint is that the shaft is a D-shaft and not a spline, but I think it probably won't matter in the end. Can't wait for the car to work. I checked the motor and while I have no way of checking the torque rating, it seems relatively accurate. Considering the price I wouldn't mind if it really only puts out 75% of "nominal" torque.
