I'm using it to manually set the idle on my jeep thru the idle air control, I'm using a 2005ish 70mm throttle body on my 1999 wj, my jeeps never idled so smooth. This thing is cheap in price but high quality not noisy has good speed control and top quality performance.

Product works as intended, but the Motor +/- and Power +/- that are engraved in the case are incorrect… there was a sticker placed adjacent to the engraved text that contradicted the engraving, and after some testing, I determined the sticker to be correct.

I hooked up the positive and negative wires according to the stamped markings on the housing before reading "ALL" the reviews. As soon as I conected it to the battery it immediatly fried something on the circuit board and destroyed one of the capacitors. The replacement is working fine now.

I used this motor controller with a kids power wheel 18v upgrade. It was working great untill I went a little crazy pushing the dual motors to max power and blew the 30a fuse. Was my fault, as I knew I was pushing the motors to their max draw… but I bought a new pack of fuses and plan to dial it down a bit next time I let my daughter cruise around in her upgraded Red Mustang which now speeds around nearly twice the speed it had been.
