I bought this motor to use in my filament respooler for 3D printing. My first impression is that it is powerful and has a lot of torque but it is loud. I assume the gearbox is making the noise. You cannot turn this by hand as you might assume knowing it is a 70:1 gear ratio. When you take the power off, it stops right away. (like a brake almost) Actually, even if you turn the down the speed, it throws my filament around a bit as if you had hit the brakes. I would give it 5 stars but it is a bit loud and was a little more than I expected to pay. I am happy that it was available though and it is about perfect for my project. It has a nice D shaped shaft which is perfect. There is a + on the back near one of the terminals indicating that it is the positive terminal. I got 2.8mm female spade connectors and used my Engineer crimper (Similar to IWISS crimper) to crimp the proper ends on. Doing the electrical crimp then the insulation crimp separately is always my preference.
It is a little slower than I expected. I got a nice inexpensive speed controller for it. At max speed it is slower than my cordless drill by quite a bit.
I hope this motor works for a long time. It will run constantly for 4-5 minutes at a time and sit for days or weeks in between. I used to respool using a drill at about 2/3 speed in 2 minutes. This is slower but I get better results.

Powerful 12v motor. A bit expensive. Kind of loud.
