The 3200dpi Pro-Optic R2 Gaming Sensor plays in the Champions" League of optical sensors, offering lag-free precision. We increased maximum speed to 130 inches per second and raised maximum acceleration to 30G. And like the current generation of ROCCAT gaming mice, the polling rate clocks in at an unprecedented 1000Hz. Comes with a feature-rich driver package, allowing precise adjustment of the sensitivity and dpi settings. All seven buttons plus the mouse wheel can be assigned a multitude of functions and custom macros, as well as predefined ROCCAT Presets. The Creating Game Profiles option makes things easier when starting a game, as the Game Profiles function automatically loads settings specific to the particular game during start-up. The Easy-Shift[+] button doesn"t just give you access to seven mouse buttons plus the mouse wheel - you also get access to 16 additional functions at the touch of a button. The Easy-Shift[+] button is similar to the shift key on a keyboard. If you hold down the Easy-Shift[+] button while pressing one of the other standard mouse buttons, you can program a second function (dual-assignment). Sound Feedback - The mouse informs you of any changes to the dpi, profile or sensitivity settings by reading them aloud. A multicolor LED system allows the mouse to light up in seven different colors - plus the mouse can be further personalized with color rotation and other lighting effects using the driver. You can even assign colors to profiles, so when you switch profiles the color changes, too. The Kova[+] sits nicely in both the left and right hand. Thanks to a slightly raised ridge on the upper casing, you can control the Kova[+] with maximum precision. The Griptech side areas extend all the way to the top of the Kova[+], letting you hold the mouse securely when lifting it. Soft-Touch Coating offers amazing grip, complementing the non-slip performance of the familiar solid rubber Griptech side areas.
