  • Optimized Grips for Gaming  - The MM520 is ideal for those who use a claw grip, best for RTS games. Rubber side grip and a ring finger rest ensure higher responsiveness and precision during
    competition, while an ergonomic body gives long-lasting comfort for those all-night gaming sessions. Perfect for the hectic chaos of RTS games, the MM520 is built to make the most out of your claw grip.
  • Precision Sensor - Fitted with the Pixart PMW3660 optical sensor with an adjustable DPI up to 12000. That’s a whole lot of DPI, which means lag-free 1:1 true input – every movement counts. No lag, no acceleration – all awesome.
  • Rugged Quality -The MM530 and MM520 are built to withstand serious punishment. The rubber grips are built to last with new a new and improved texture design. Key points on these mice are composed of longlasting, wear-free PBT plastic, some of the hardest plastic used to build hardware today to make
    sure these mice stay looking, and performing well even after years of use. Additionally, Omron
    switches under the buttons are graded for 20 million clicks and a ALPS scroll wheel encoder make
    sure these mice will remain accurate and true through the end.
  • Fully Programmable - Set your default DPI, and four separate DPI settings in 100 DPI increments, anywhere from 100 DPI up to 12000 DPI. An onboard DPI switch allows you to make On-the-Fly adjustments in precision, allowing you to make changes in your precision level in a snap.
    Besides standard button assignments adjustments both mice also feature our “Tactix” feature, which allows you to add to every button a second layer of assignments, in theory dubbeling the amount.
    Or adjust the RGB Illumination in three zones to give your greatest victories a nice cool factor.

EG Quick Tips

The great DPI debate... is uber high DPI needed or not? At the end of the day, this is dependent on what your needs are.

We recommend going with a mouse with a decent DPI rate complete with a control switch feature, which allows you to change between preset DPI rates, giving you the best of both worlds!
