I love these motors. I currently have 4 and have had them for about six months. They work great for what I've used them for and never had a problem. Just make sure you buy the right motor driver and power supply that will actually draw enough current to drive those motors. I've been using drivers with too low an output current resulting in it not using its full torque, so it kept skipping steps. I've fixed this issue now and they work like a charm. Pros: Smooth, very accurate steps, no need for a radial encoder if set up and used properly. Disadvantages: none. Update.
