Review on RioRandTM Upgraded 6V 90V Motor Controller by Jasneet Jazzy

Goes from off to full very smoothly. I tried two other PWMs, neither of which worked except just off and full. Used to control the flow of water from the fresh water tank. Accidentally soaked in water during use and it still works like a champ. I don't recommend cheaper alternatives, just buy the one that works first. Happy with it, will make a backup just in case, but definitely stick with it. Nothing particularly warm and noisy.
