Great gearbox
I bought four of these for a 4wd robot platform. These are very impressive with the faulhaber motors they give impressive torque and could be used as direct drive (no pillow block needed) on a 10lb platform. My only complaint is that the output shaft has a bronze bushing not a bearing but that is just a minor detail.

Good stuff
Very smooth, very high torque and solidly built. Well worth it, if you can find the motor that goes with it (AllElectronics used to have it, but I can't seem to track it down now...)

Good enough for a lot of applications
I bought a large number of these to put in kits for a group of middle school aged kids to experiment with. I bought the matching micromo motor which is a fantastic deal for that motor.

A couple things to note. The pinion for that the motors have attached is metric module 4.5...which is nearly impossible to find, so you really need the motors in order to use the gear head at all.

Second, the motors offer a lot of power, but the gearhead planetary gears are not steel. They are either pot metal or aluminum, and really do not match the capabilities of the motor. In low torque situations they are fine and we have used them with good results.

Third, the gearhead is quite loud for a planetary gear. So be aware that if your application need very quiet operation, then one of the other fine motor gearhead combinations offered by All Electronics is probably a better match.

Solving the drive gear
As the teacher mentioned finding a 4.5 Module gear is a real problem. I solved the problem by buying an extra gearhead. Remove the cover and remove the first layer of planeteatary gears. A second layer of pinion gears are thicker. They are 4.5Module. I removed one and made a stub shaft that was turned for a press fit with the 4MM hole in the pinion.
