Logitech G710

With high-performance, low-noise mechanical keys and adjustable dual-zone backlighting.
The mechanical keys on the G710+ deliver gaming-grade responsiveness and tactile feedback superior to rubber-domed keys. With an actuation force and distance of 45 g and 4 mm, respectively, the keys are optimized for rapid command entry. Plus, the keys have been tested for durability to a 50 million cycle life.
Quiet, non-clicking key switches and a built-in dampening ring underneath each keycap significantly reduces the distracting noise coming from your keypresses without sacrificing responsiveness.
Easily locate keys—even in low light. The entire keyboard is backlit in white LED light and adjustable to one of four brightness levels plus “Off”. For better visibility of the WASD and arrow keys, their brightness can be adjusted independently from the rest of the keyboard.
