Review on Sun YOBA Controller Intelligent Regulator by Ryan Barton

The device works great. The only "complaint" I have is that the screen is difficult to read from an angle. Unfortunately, where I installed mine, it's almost impossible to look directly at the display. Overall, however, it does a great job of regulating my auxiliary battery. It's definitely more than I need for my setup, but for the price I don't think you can beat the quality. I had to replace my previous device (BlueFire PWM) which failed after just a few months of use.
