The Logitech MMO mouse is a simple-to-use gaming mouse which has been designed primarily for playing MMOs or massively multiplayer online video games. With 20 buttons which are MMO tuned, the Logitech G600 can be easily customised to suit individual and the game being played. A unique feature provided by the Logitech MMO mouse is the twelve buttons positioned on the thuMB panel. These buttons are designed to give the players fast, no-look navigation around the game being played. The G-shift, ring-finger button on the Logitech G600 will also immediately double the number of actions which can be performed with every button, and this immediately adds an extra dimension to any game. To help reduce click fatigue whilst engaged in long, multiplayer gaming sessions, the gaming mouse has sculpted shape and tuned buttons which eases the pressure on the gamer’s hand and joints. The Logitech MMO mouse is compatible with the Windows Vista, 7, and 8.
