The iMouse X1 is equipped with an optical gaming sensor to ensure pin-point precision in different usage environments. Additionally, different color illuminations allow users to work or play in dark environments. The ambidextrious design and textured surface on both sides of the mouse provide better grip for both right and left hand users. The built-in DPI switch button offers the convenience of switching between different DPI levels (1000, 1600, 2400, 3200) and colors (white, green, blue, red) all at the tip of your fingers!
