Performance
* Interchangeable Grips: Use the included XL and Precision grips to get a fit and feel that's best for your playing style. The satin texture and fuller shape
of the XL grip add extra comfort while the DryGrip technology plus compact shape of the Precision grip give you unmatched fingertip control.

(including keyboard macros, dpi settings, and LED colour) on the mouse and play your way—without additional software installation*—on any computer.
Control
* MicroGear™ Precision Scroll Wheel: Use Logitech’s exclusive MicroGear™ scrolling technology for precise, click-to-click scrolling—perfect for quick
weapon selection. Or switch modes for frictionless, hyper-fast scrolling.

multiple sensitivity levels between 200 and 3200 dpi, without driver installation.
