"I purchased this motor along with the rest of the power functions to power some RC battlebots. I have no regrets to buying this motor, powerful, strong, rugged, and for me, when hooked up to the PF battery box can last me for months! Most people say that this motor is weaker compared to the mindstorm NXT motor, that is untrue. They both deliver the same amount of torque just the NXT motor is geared slightly abit lower than this one.
Overall It was a great buy and I would recommend not only getting this motor, but also looking into the rest of the PF accessories as they are all a necessity for anyone looking into powering their creations."
