"When it comes to gaming, accuracy is the difference between life and death. A quick response rate, like that of the G400s, is crucial. Two brave gamers take on the challenge of aiming for a bull's-eye 50 ft. away. If they miss it, they risk destroying a dearly beloved item. Building on the powerful legacy of MX518 and G400, G400s features exclusive Delta Zero sensor optimizations for high-accuracy cursor control. Whether flying across the screen or honing in on one pixel, the 4000 DPI sensor responds accurately to your hand movements. The LED-illuminated sensor is designed to go beyond simple eye/hand coordination, diminishing the thinking required to move your character, adjust your scope for sniping, select RTS units, or direct MOBA skill shots. Gaming conditions torture typical mice. G400s is designed to endure. Upgraded primary mechanical microswitches are rated to a 20 million click lifespan. Low-friction polytetrafluoroethylene feet are tested to last an amazing 250 km. Whatever you can dish out, G400s will stand up to it. - Make the right moves in any game situation. Shift through multiple DPI settings for quickly selecting on-screen options or scanning the game map (up to 4000 DPI) or downshifting to make pixel-precise sniper targeting or unit selection (200 DPI) using dedicated buttons conveniently located above and below the scroll wheel"
