Rod S****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.
Sam N***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.
Jim S**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.

Planetary gears are slightly expensive compared to traditional gears. However, they guarantee a high ROI.
Design is quite complex thou they are efficient and still easy to maintain.
From this, you can see that the planetary gearbox has many advantages.
