Cooler Master engineers went to work on how to effectively design a keyboard with superior switches and the brightest LED backlighting. We gutted the interior and redefined RGB backlighting by modifying the printed circuit board (PCB) with small cutouts to let the LEDs sit snugly against the switches. That means we're still able to use genuine Cherry MX switches with their RGB housing AND larger, brighter LEDs. The concentrated light under the keycaps will let your keyboard's LEDs pop and shine with vibrant colors. No dull muted colors here.

The MasterKeys Pro L radiates any color you want. Change and customize the color with or without software. LEDs include multiple modes of operation, including Color Wave, Breathing, and unique responsive effects.

The MasterKeys Pro L Crystal Edition lets you stand apart from the rest. Transparent keys and casing let your custom illuminations radiate brighter than ever before, while the frosted coating protects from glare.

The MasterKeys Pro is outfitted with the most powerful ARM Cortex M3 processor found in keyboards in the market right now. Clocking in at an impressive 72 MHz, the processor is 25% faster than keyboards that use Cortex M0 processor, which greatly unlocks the potential for the MasterKeys Pro On-the-fly System. Save and execute commands and macros instantly. No loading. No waiting. You'll beat your opponent to the punch every time.

The MasterKeys Pro utilizes the processing power of the ARM Cortex M3 for its advanced On-the-fly System. LED lighting modes, repeat rate adjustment, multimedia keys, macro recording, combined with four profile keys, enable you to control all aspects of the keyboard right at your fingertips.
