This motor has about 15 RPM at 18 volts with plenty of torque. It has a square output shaft with a hole in it which makes it easy to attach things. It has a loud click with each revolution. This click remains even if the switch is removed. I sliced the electronic board off with my Dremel and connected directly to the motor. It is very important to connect + to +. If reversed the motor itself will run in reverse but the gear train will be destroyed. To me it is well worth the price.
The mounting holes are “heat welded” but can easily be drilled out with a 5/16 bit. You can open the cover and access the drive train and remove the spring cog that makes the noisy click every rotation. The motor will then run continuously. You can glue or use nuts and bolts to reattach the cover. I attached a 6” arm to the square shaft and taped (2) 9-volt batteries as weight and have the following data.
6 VDC-4.5 RPM
9 VDC-7.5 RPM
12VDC-12 RPM
12VDC draws 90 Ma current
Gear train is a little noisy but runs smoothly once you take out that spring cog
When you remove power, the gear train holds position
