Featuring a Counter Strike Global Offensive unique design, the SteelSeries Counterstrike GO is an optical, ambidextrous mouse designed for all three grip styles: palm, claw and swipe. Based on the Steelseries Kana mouse, the functionality, ergonomic button layout and size was perfected alongside SteelSeries professional gaming teams, who also tested and validated the precision and power hidden in the Kana’s modest exterior. Make no mistake; this mouse was built for consistency and accuracy even in professional tournament conditions.
