Extra-large mouse pad: G840 unifies the desktop into one gaming surface. The consistent height across your desktop allows you to place your keyboard in far more positions, without interfering with your mouse, for added comfort and options Performance-tuned surface: G840 has a surface texture that delivers the optimal contrast for translating mouse movement into cursor movement even at high speeds. This performance-tuned surface provides peak accuracy and consistency for gaming mice Moderate surface friction: Consistent surface friction gives you feedback to “feel” mouse movement, allowing you to accurately target using muscle memory and optimise both high-speed flicks and low-speed control Rubber base keeps it in place: Low-DPI gamers make sweeping, fast hand movements, especially during intense gameplay. The rubber base keeps the entire surface in place, providing stability and preventing the cloth from bunching up to maintain smooth mouse movement Durable tube for transport: G840 is durable and flexible enough for easy travel with an extra-large mouse pad. Just roll it up into a small roll and place into the included transport tube. Take mouse and keyboard comfort with you
