"Sorry I am back. Today gearbox 2 broke. The same issue as the 1st, the trigger trolly stop broke. That's 2 of the 3 that broke only a few games in. I still have one gearbox working but since 2 of the 3 have broke its only a matter of time before it breaks as well. Please customers these reviews are important. If these reviews were in place before I bought these I wouldn't of purchased them.

"Ok update on this gearbox. 10 games in the trigger trolly stop broke. I bought 3 of these gearboxes and now one is trash. I assume the others will do the same thing. Cheap pot metal shell.

"I ordered 3 of them and installed them in combat machine bodies. All chronod 350ish. Only issue was the positive motor wire was short. 99% of the time both wires are supposed to come up the backside of the grip for proper motor alignment. So with the wire being short, the only way we to run the positive up the front side of the grip but then the motor wouldn't fit because of the wire. Once I extended it 1.5 inches everything was good.

So far so good. No issues.
