With the Logitech® Performance Mouse MX™, you have the power to achieve. You can track precisely on more surfaces – even glass tables (4 mm minimum thickness) – thanks to Logitech® Darkfield Laser Tracking™. Your tiny Logitech® Unifying receiver stays in your notebook. There’s no need to unplug it when you move around, so there’s less worry of it being broken or lost. You can recharge your mouse through your computer or a wall socket, even while you’re using it, with flexible micro-USB charging. You’ll fly through long documents with hyper-fast scrolling. And its sculpted, right-handed shape with integrated thumb controls puts everything under your command.
