I used this to motorize the Z axis of a laser engraver. Slow, precise movement for millimeter adjustment. I used a 4-wire JST-XH connection and plugged it directly into the Z-axis slot on the board. Works perfectly.

Purchased to automate macro setup. It is durable and virtually free of play. Best of all, the base is pre-drilled with screw holes, making installation very easy.

When you get something that works, it works well. The challenge is getting one that works. I would say they have very poor quality control. Don't expect to get what you want in a hurry, because you'll have to keep trying until you get something that works properly. But I kept going until I had two that worked properly.
