SteelSeries Ikari Laser Gaming Mouse- The award-winning SteelSeries Ikari Laser Gaming Mouse features programmable macros for RTS and MMO gamers and a high precision sensor suitable for FPS gamers. The SteelSeries Ikari Laser Gaming Mouse is the result of 15 months extensive research of ergonomics, technology, shape, motion, hand grip and play styles by gamers. The shape, materials and specifications of the SteelSeries Ikari Laser Mouse are based on input from professional players from Team 3D, compLexity, mousesports, SK Gaming, Team NoA and other world-class gaming organizations, who collectively represent the world's most accomplished gamers in Counter-Strike and other gaming disciplines. The SteelSeries Ikari Laser Mouse features programmable macros for RTS and MMO gamers and a high precision sensor suitable for FPS gamers. Furthermore the Ikari Laser is completely driverless which enables the mouse to remember settings and macros when plugged into tournament computers - without installing any drivers or software. The advanced SteelSeries XY2 laser engine supports resolution settings with increments of only 1 CPI, which for the first time ever gives the user the ability to fine tune the mouse exactly to their personal reaction pattern. Set your windows and in-game sensitivity to default and set the CPI on your hardware instead of forcing software calculations. With the built in LED display in the bottom of the Ikari Laser you are able to adjust your CPI anytime, anywhere - you are completely independent of software or drivers. The gaming grade engine used in the SteelSeries Ikari Laser Mouse utilizes a new way of analyzing tracking, reaching 40,000 samples per second (or around 5 times the speed of conventional laser technology).
