Review on Greartisan 6V-90V 15A PLC DC Motor Speed Controller PWM Variable Speed Regulator Governor Switch CCMHCN With Speed Control Knob by Johnny Black

It’s been about 4 mths. No issues. I would have given it 5 stars. The only issue I had with it should have been trivial. The nut that fastens the speed control knob to the dash wdid not come with it and the threads on appear have been cross threaded.?Maybe a return. Don’t know. However the box works flawlessly. Just have to figure out how to attach the knob assembly to my dash board.
