The Logitech G502 X Gaming Mouse introduces LIGHTFORCE hybrid optical-mechanical switches for the main left and right buttons, which provide higher levels of speed and reliability while retaining the feel of mechanical switches. It is equipped with the HERO 25K optical sensor that delivers pinpoint precision with up to 25,600 dpi of sensitivity. The reversible DPI-shift button located on the thumb rest lets you switch settings on-the-fly to adapt to different situations. Or you can remove the button altogether and replace it with a cover. Logitech G502 X comes with 13 programmable controls and onboard memory for up to five profiles. You can customize this lightweight mouse for different games and applications.
