Review on Cooler Master 6-Preset Modes Addressable RGB Fan Controller - Enhanced with 7 Vibrant Colors and Thermal Detection Mode for Fans and Air Cooler by Ron Houston

I bought this because I made the mistake of buying separate CM mf120r Argb fans (instead of the 3 pack which included this one or the Pro which is RGB only and supported by my mobile device) , connecting with them was easy, figuring out how to use the controller when it's in the case varied a lot so I decided to just leave the controller outside until I figured out which MasterPlus software the controller is compatible with . IF you connect it to a USB port (Micro-USB). The quality of the material seems good, the plastic body of the controller feels a bit flimsy, the buttons aren't as crisp as I'd like, but they do the job.
