Cooler Master MasterKeys Pro L RGB Wired Gaming Keyboard - US English Layout - Red Switch by Cooler Master

MASTERKEYS Pro l
Get the best of both worlds with the MasterKeys Pro L and Pro S: the brightest LEDs and the best tactile feeling that gamers have come to love. We completely redesigned the interior to fit both Cherry MX switches and big, fat, LEDs that can radiate 16.7 million colors. You also get on-the-fly macros, profile support, and easy-to-use software - all in a sleek, minimalistic design.

The Best of Both Worlds
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.

Brilliant Illumination
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.

Processing Power Unleashed
25% Faster
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.
