Logitech Mouse M100 gives you just the basics for comfortable, reliable control of your computer. It’s built by Logitech – the mouse experts – and comes with the quality we’ve built into more than a billion mice. There’s no software to install. And since it’s corded, you can just plug the cable into a USB port and use it right away. The full-size, ambidextrous shape means your hand will rest comfortably, while high-definition optical tracking (1 000 DPI) means you’ll get responsive, smooth cursor control for precise tracking and easy text selection
