The Sunbeam Rheobus Extreme fan controller is somewhat unique in that is provides users with six channels with variable voltage from 4V to 12V 0V to 12V. Many other models have maybe four channels at most, and some that have six do not even provide complete variable speed control on all the channels. Add to that the fact that each channel supports up to 30 watts and the Rheobus Extreme stands out from the crowd. Each knob lights up with blue LEDs and changes in brightness as the voltage is raised or lowered, but they may be too bright for some users.

There were a few things that I did not like about the unit. The front panel is aluminum, but it is covered with a clear plastic bezel. This may mean that the front might not match all the black cases out there, especially the aluminum ones. The other thing that may be an issue is the brightness of the LEDs. However, both concerns are mostly a matter of preference and each user will have their own opinion.

Overall I am pleased with the updates Sunbeam has made with the Rheobus Extreme, as those updates fixed my major concerns. More importantly, I am pleased with Sunbeam and how they listened to my criticism and worked to bring their customers a better product. I have dealt with other companies before that did not take kindly to a reviewer's advice. However, Sunbeam took a different route: they listened and went back to the drawing board. When they came back, the new version was much better and definitely put my concerns about build quality to rest. With the new updated version I can officially give the Rheobus Extreme the "Recommended Award" it deserves.
