Wireless and professional-level LIGHTSPEED technology, advanced LIGHTSYNC-RGB technology and new, low and high-performance mechanical switches - the G915 is a breakthrough in design. Crafted with care and sophistication from premium materials, its beautiful shape, solid body and good performance are second to none. GL Clicky switches feature audible clicks and clearly felt tactile feedback. Mechanical key switches are not only more durable, but offer faster and more consistent keystrokes than standard membrane keyboards. They respond with sound and sensors during control and immediately report keystrokes.
