TUNED TO PRO-GAMERS SPECIFICATIONS Accuracy and durability for the highest levels We worked directly with professional MOBA players to design features and playability from the ground up. Delta ZeroTM sensor technology ensures accurate tracking while button durability is built to withstand high speed clicking for hours on end.
ON-THE-FLY DPI SHIFTING Better control of how you game Make the right moves in any game situation. Shift through up to 4 DPI settings, from pixel-precise targeting (240 DPI) to lightning-fast maneuvers (up to 4000 DPI).
METAL SPRING BUTTON TENSIONING SYSTEM Improved button response and feel MOBA games are some of the toughest games on mouse buttons, with commands regularly issued multiple times per second. The metal spring tensioning system keeps left and right mouse buttons precisely tensioned to improve response and feel, making in-game actions fast and accurate click after click.
DURABLE AND LIGHTWEIGHT Designed for maximum play time The lightweight design, ultra durable switches tested to 20- million clicks, and super low friction feet enable you to be comfortable no matter how long competition lasts.
SIX PROGRAMMABLE BUTTONS Customize to fit your style of game play. Achieve great results with the default configuration straight out of the box. Or, set up one-button triggers for actions that typically require digging into menus. Put push-to-talk communications in easier reach. Temporarily down-shift DPI for sniping. Reassign any game command or multi-command macro to any one of six programmable buttons with Logitech Gaming Software
