They should be worth it, as the motor/gearbox inside it is likely to be very similar to the motor/gearboxes in a lot of other low-priced cordless drills which have been used several times in many robots with high levels of success.

Some people seem to be unfortunate in the sense that drill motors don't tend to be reliable for them and they go through several replacements. It could be the way they are mounting them etc or it could just be that for whatever reason, their robot doesn't like drill motors. But cases like these are significantly less than cases where people have had success with drill motors.

I tend to use drill motors because they are light, cheap, moderately fast and come pretty much ready-made. I also have my own preferred way of mounting them (that is low-cost for working on a budget) that seems to work well. Thanks to Robo Challenge, attaching wheels to them is a doddle too.

Basically they are a good all-in-one option for drive motors. You could go for more powerful motors, make your own transmission system and have an extremely powerful and (probably) fast drive system, but for anyone who doesn't have the budget or facilities to make something like that, these are ideal.
