As with previous Master series mice, the wheel switches automatically between free spinning and precise line-by-line scrolling depending on how fast you move the wheel. The main wheel uses a technology Logitech calls “MagSpeed,” employing contactless electromagnetic switches rather than mechanical ones, for accuracy and long life. Right away, you’ll probably notice that the MX Master 3 has two scroll wheels: a main vertical wheel and a secondary thumbwheel. It’s such a nice feature that once you experience it, you’ll become painfully aware of how few other mice offer this support. It perfectly fits your hand’s natural resting position, with a wide, flared base that supports the base of your thumb. Nowhere is Logitech’s attention to ergonomic nuance more evident than in the design of the MX Master 3. Logitech MX Master 3 Eric Ravenscraft/CNN Your CNN account Log in to your CNN account
