So far they work fine...

The media could not be loaded. The product was adequately packaged and arrived on time. After researching many similar products, this one provided just what I needed, high torque, slow speed, and a drive/control (sold separately). I'm using it to turn a compost tumbler which I've calculated to require between 40nm and 50nm torque to turn. This motor was one of the few rated to handle this. And it works like a dream.

The product descriptions might not make you understand, but the motor itself has an adjustable "rotation counter" for both directions. You can flip open a small water-proof lid to access the two dials. One sets the max rotations in the fwd direction, and the other reverse. I've set them to rotate my compost tumbler 3 full turns, at which point it auto-stops. Next time, I flip the controller switch in the other direction, it reverses polarity, and my tumbler rotates 3 full turns in the other direction. This arrangement is working well.

The reason I only gave it 4 stars is, my motor has NO markings, no labels, no stamped values.... nothing on it to identify which model I got. They sell 2 models, a 60W and 80W I believe. I paid more for the 80W, but they look identical, so I can't tell which one I have.

Thanks works great,limiter is insde just need a timer

that one good

Used this very strong but slow motor to open close my pool cover with 3D printed coupler

So far has worked great
