I'm not a fan of ToughBoxes (though I do like the name). Our team once used them regularly, but not anymore due to consistent problems and low performance. The ToughBox is very heavy, and has too much (IMO) gear reduction for most uses. Maybe it's a good ratio for very large, high-traction wheels, when you value torque over top speed. The worst part is that it is too easy to put something together incorrectly in the ToughBox (encoder mounts, etc.), and not know it until further down the assembly process. Then it's a lot of work to disassemble, fix, and re-assemble. That, unfortunately, happened to us more than once.

The CIMple gearbox in the KoP has been much better for us.
