"This thing is a great drop-in option, especially for PDWs. It has thick wires that are easy to bend for better fitment and provide a bit of a quicker trigger response (just a bit). Similar to what another reviewer said, I think, I DID have to shave part of the trolley down so my trigger lined up better. And the wiring is a little short coming out of the back of the gearbox, thus high praise for PDWs and 9mm replicas. Otherwise it's probably a good idea to get a wire extension for a buffer tube.

"Just installed this wiring assembly and here are the pros and con's.
Pros-quicker trigger response , higher ROF ,clean look.... Cons- the wires are too short barely had them reaching half way down my buffer tube had to have the wires lengthened , the wires get very hot very quickly with 11.1 lipo 25c anything under seems to be ok but could be the fact I'm running the g&p speed motor they are power hungry getting a high torque motor may resolve the issue since they are more efficient. All in all great product just needs Lil thicker gauge wires and longer rear wiring by about 3 to 4 inches would be perfect .
