Works like a Charm

Fantastic motor nice rpm speed great if you're building a rover or tank also gives you the torque you would need to go direct drive attaching the motor directly to the gear and or wheel

Good Motor

Good motor and lots of torque.

Strong motor!

A little on the pricey side but well worth it if you need a lot of torque. I would like to see them offer the other ratios that are available however so that my purchases can stay within Canada.

Long term reliability!

I have purchased more than 25 of these gear motors from Robot Shop and all of them have worked great. I'm very happy with the quality.
