Review on Enhanced Efficiency and Protection of RioRand Controller by Mario Anderson

This controller worked right out of the box. Runs smoothly from low to high speed and seems pretty stable. Although no documentation came with the device, that's the only reason I gave it four stars for "ease of use" instead of five. However, most of the information you need can be found on the Revain website in the item description and any information not listed (e.g. remote potentiometer pinout) is easy to find.
