Most Helpful Customer Reviews
Works great as designed. Clean square wave. The only issue is the speed control pot was not crimped well and the guts of the pot were visible and loose. We removed the knob and tightly crimped the housing of the pot and now it feels solid. The pot itself is not mounted on a bracket and can easily be broken off the board so heads up there.
Many thanks, great unit
Excellent little motor PWM controller. Used it at multiple voltages and works nicely. My only complaint is you cannot connect all the wires without removing the top cover and that is why it is marked to 4 stars otherwise it's great. I recieved at a discount for review
