The G9 Laser Mouse is built with advanced customization technology so you can tune your mouse for your playing style.  It comes with two interchangeable grips from which to choose for your preferred comfort.  A 3200 dpi full-speed USB laser engine with adjustable dpi, as well as onboard memory that stores up to 5 mouse setting profiles, give you the most advanced performance.  For more control, the G9’s weight tuning system allows you to add up to 28 grams of additional weight, while the exclusive MicroGear™ Scroll Wheel lets you switch between modes -- click-to-click and hyper-fast scrolling.  Finally, custom-color LEDs let you customize the G9 look for a mouse that’s all your own.
