COOLER MASTER MASTERKEYS PRO L
Cooler Master's new MasterKeys Pro keyboard line comes in two variations: L and S. The Pro L is a full-sized keyboard, while the Pro S is a tenkeyless option. In addition to a numberpad, the Pro L also gets four additional profile switching keys in the top right corner.
Both keyboards use a simple, matte black two-part plastic frame, with a steel plate inside for stability. The plate is painted white to better reflect the LED lighting. On the bottom of the keyboard, two flip-out plastic feet let you adjust the typing angle. The keyboards connect through a detachable braided Micro-USB cable, which is nice since you can replace it if it gets damaged. Both keyboards are available in Cherry MX Brown, Red or Blue switches and use standard Cherry MX stems. On all three versions, the switch housing is transparent, which helps the LED lighting shine through. Cooler Master has also redesigned the PCB with smaller cutouts to let the LEDs sit snugly against the switches. This results in much brighter and more uniform backlighting. In fact, the MasterKeys Pro L is probably the brightest keyboard in our shootout. The keyboard also has full N-key rollover and anti-ghosting.
Inside the keyboard, a 32-bit ARM Cortex M3 processor and 512KB of memory are included for storing and playing back custom macros, which can be programmed on the fly without the need for any software.
The ARM processor also controls the keyboards lighting options. By default, pressing Fn and F4 will cycle through various patterns and modes, including wave, static and reactive effects, as well as some silly options like being able to play Snake on the keyboard with the arrow keys. In most modes, you can control the color using Fn and F1, F2 and F3, which represent the red, green and blue channels respectively. You can mix and match these levels to create pretty much any color. You can also create your own per-key pattern. In this mode, the Fn key will light up in the currently selected color, and you then tap any keys you want in that color.
While the keyboards don't require any software to use, Cooler Master does provide software for users who prefer an easy-to-use GUI to customize their macros or lighting options.
The MasterKeys Pro L has a braided removable Micro-USB cable.
