Features: Adds the extra gaming benefit of MULTY KEY ROLLOVER. This mechanical gaming keyboard registers each key press independently so the character is recognized regardless of how many other keys are hit at the same time. This blue switch mechanical keyboard is the best choice for users that rely on the tactile feedback and satisfying "clack" emitted by the switches underneath the keys for accuracy and speed. The key caps themselves are concave to fit the natural curvature of your fingertips, which results in a much more comfortable typing experience. Built-in 6 MODES gaming keys LIGHTING-UP PATTERNS(ripple, marquee, scroll, Z-type, breathe etc) enhance the exciting gaming feeling.
