We used them before and had some unusual performance drop that made it appear like burned out a single pole. Once we figured it out and replaced it the motor was fine.

I would de-rate the banebots numbers on them a bit based on our experiences as well. The advantage to using them is they are cheap to replace < $6 each and for around $30-40 from Banebots they have planetaries are available in many ratios for these motors making them easy to adapt to a mechanism without much effort.
