The Logitech Performance Mouse MX is a high-performance machine that provides accurate and precise tracking on virtually any surface – even glass – thanks to Logitech Darkfield Laser Tracking. And the tiny Logitech Unifying receiver frees you from the hassle of plugging and unplugging the receiver when you're ready to change locations, plus it can be paired with your favorite keyboard for streamlined wireless connectivity. Add to that a flexible recharging system, hyper-fast scrolling, and four thumb-buttons for interacting with apps and files and you've got a mouse that knows no limits.
