Funny story actually. We were presenting our robot at the Franklin Institute and let people drive our robot. Kids specifically. I believe they managed to burn out this one motor in the front about 4 times before another team let us replace the normal wire with a thermal one.
Never had another burn out. Haha so we bought 6 more! They really are a money saver campared to all of the motor replacements. (I think we had a total of 7 burnouts this year) = $220
