Cooler Master MasterKeys Pro L Keyboard Review: Spectrum Ad Infinitum

Cooler Master MasterKeys Pro L KeyboardThe Cooler Master MasterKeys Pro L is a full-size keyboard that defies convention with its bright Cherry MX RGB LED backlight on a traditional conservative frame. This dichotomy is inherent in the MasterKeys Pro L’s design for it is comfortable for both work or play; as a productivity workhorse or as a PC gaming controller. It has NKRO over USB functionality, dedicated live switching profile buttons, live macro recording and offers ten-level per-color channel RGB adjustment via key combos which can extend further to a 16.8M wide color gamut with the MasterKeys Pro L software installed. It is new but it is familiar. It is aesthetically muted but it is colorfully loud. It is flexible but it is precise. It is a master and a servant at the same time.

More than a name change from the QuickFire series, the new MasterKeys Pro L also sports new box art styled in the same vein as Cooler Master’s current “Make It Yours” crop of products. A full-size view of the MasterKeys Pro in print lets buyers know that this is the “L” full layout version as opposed to the “S” tenkeyless version. Localized layouts are available, indicated with a sticker on the side and the switch type is also printed on the box cover to separate it from the two other switch options.

Inside, the actual keyboard is housed in a protective bag while the accessories are underneath the partition at the top.
