Review on RioRandTM Upgraded 6V 90V Motor Controller by Chris Santos

After reading another customer's detailed review on this product, I purchased and installed it to control the speed of my Awesome Fan in my RV. IMHO the fan just runs too fast even on the lowest setting and you only get three (H, M, L) settings which just isn't enough. With this unit installed I can now infinitely adjust the fan blades from maximum speed if I want, which is great for moving small amounts of air in and out of my camper. Along with the lower speeds comes a much quieter fan. Thumbs up for this product!
