Cougar is expanding its gaming keyboard lineup with the entry-level 500K. While its bigger siblings, the 700K, and 600K, feature mechanical switches, the 500K offers gaming-grade membrane keys. The keyset resembles the 700K, more than the 600K; with its nine macro keys. The keystroke repeat function lets you repeat specific keys, at 2~8 times per second. The 500K features full N-key rollover, letting you press any number of keys simultaneously, over a USB connection, without keystrokes that don't register. The 500K features an "FPS-friendly" palm-rest. It however, lacks the brushed aluminium cladding found on Cougar's other two keyboards. Cougar didn't announce pricing or availability.
