The Solarbotics GM17 Gear Motor is designed for low-voltage power-efficiency, but it isn't scared of generating a bit of torque. And the output shaft is shaped just like the GM2 - Gear Motor 2 Offset Shaft for full accessory compatibility! It's a small, slow, power-efficient but torquey motor, a bit bigger than its more powerful brethren.
Pretty much what I expected. Only complaint is that the wires are rather small and made them difficult to work with. They broke during soldering a few times.

Great!
These little gear motors are great, quiet and just the right speed for my application.
