Logitech Mouse M90 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 (1000 dpi) means you’ll get responsive, smooth cursor control for precise tracking and easy text selection.
