Overview

Brand new Gamers weapon from Logitech....  The G9
 
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.
    * 3200 dpi laser engine with Full-Speed USB: Get uncompromising speed and accuracy from a high-performance Gaming-Grade laser engine—plus instant cursor
response with Full-Speed USB (up to 1000 reports/second).
    * Game settings to go: Take your personal mouse preferences with you. The Logitech G9 saves mouse settings in onboard memory—store up to 5 profiles
(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.
    * Adjustable sensitivity: Shift from pixel-precise targeting to lightning-fast manoeuvers without pausing the action. The Logitech G9 gives you instant access to
multiple sensitivity levels between 200 and 3200 dpi, without driver installation.
    * Weight tuning system: Prefer a heavier or lighter mouse? Use the weight cartridge and up to 28 g of metal weights to customise your Logitech G9 for just the right feel.
    * Polytetrafluoroethylene feet: Super-slick feet glide effortlessly across almost any surface.
Comfort and Convenience
    * Custom-colour LEDs: A colour LED display indicates the current sensitivity level and profile settings. Personalise the colour LED display by choosing from
hundreds of colours.
    * More grip styles: Swap out your grip for a new look and feel.
