Logitech’s New Mx Master 3 Employs Magnets For A Better Scroll

We’ve long been fans of Logitech’s MX line of mice, especially the Master series. They’re attractive, reliable and have found a home in both our back to school and holiday gift guides. Today the company revealed the newest additions to the family: the MX Master 3 mouse and, the first keyboard in the series, the MX Keys.

But everything’s just a bit more refined or useful now. Those side buttons, which on other mice usually default to back and forward in apps like browsers, automatically change their function based on what program you’re using. They’ll still navigate when you’re using Chrome or Safari, but in something like Microsoft Word they’ll function as “undo” and “redo” instead. That means you’ll be able to do a lot more right out of the box, with no configuration required — though you can still fuss with the preferences in the Logitech Options software.

But there’s one change in the MX Master 3 that could be a game changer for some users. The top and side scroll wheels ball are now aluminum, and instead of mechanical gears, the Master 3 uses magnets to control how quickly things scroll.

It’s definitely not perfect, and requires more effort to get it to fast scroll down than up. There is a button that triggers the quick scroll, but I don’t think many people will remember to use it. Also, 1,000 lines is just a bit too much; 500 in a shot is probably enough. And Ctrl- or Cmd-F might be more useful. But, those are minor quibbles with an overall excellent piece of kit.

The keyboard also knows to turn off the lighting when it’s not in use, illuminating the keys only when it senses your hand breaking the low level electromagnetic field that surrounds the edges of the deck. Both units go on sale for $100 each later this month.
