MX Master 3S is outfitted with our most accurate sensor ever, with next-gen precision and responsiveness. The 8,000 DPI optical sensor tracks virtually anywhere – even on glass. You can adjust your tracking sensitivity in Logi Options+ and set the right level for your workflow and monitor resolution. 

MagSpeed Electromagnetic scrolling is precise enough to stop on a pixel and quick enough to scroll 1,000 lines per second. Oh, and it’s nearly silent. The wheel’s machined steel gives it a premium tactility and enough weight to offer a dynamic inertia you feel – but don’t hear.
