I just got my new Cooler Master Masterkeys Pro with RGB backlighting and Cherry MX Brown switches. It'll be a few more weeks before I get my new desktop, so I set up the colors using the built in keyboard functions not the software. So far, very easy to use and customize. Switches feel good but need to broken in like my old Rosewill.
Backlighting looks bright and even although just like most RGB keyboards there is significant light bleed on the sides. I do prefer the backlighting through the keycaps only with minimal light bleed, but I'll get used to this.
I'll update when I get my computer and test out the software.
The keyboard uses a micro USB cable now so no more loose cable connections like my old Rosewill mini USB had. Plus, it prefers a USB 3.0 port for its power requirements instead of some older RGB keyboards that used dual USB cables. I'm glad of that.
This will be my main keyboard for now. Overall, it's a very well constructed keyboard.
