These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

Please develop more low noise gearbox and with better prices, so we can sell your products to more clients and gain larger markets. Thank you.

I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.
