  1. Robert Jackson

    I love the size and power of this motor. It’s super compact. The feel of the metal gears is outstanding.

  2. Maureen

    Used it in a golden key machine,, and it fits well. Runs smoothly with no immediate issues. I’ll update after extended use, but so far, so good.🥇🙂

  3. Andrew Tate

    Looks good out of the box. Installed according to the instructions, the gears started to spin. Tested at the recommended rated voltage of 12V, the motor can reach 20rpm. matches the description on the page.
