Logitech MX Master 4
Our pick

Logitech MX Master 4

The best mouse for work: a sculpted shape that's comfortable all day, a fast metal scroll wheel plus a thumb wheel, very quiet clicks and about 70 days per charge.

Logitech MX Ergo S Wireless Trackball

Logitech MX Ergo S Wireless Trackball

The best trackball: you steer with your thumb, so your arm stays still. It tilts to 20Β°, clicks silently and lasts about four months per charge. US shops sell it as the MX Ergo S Plus, with an extra wedge.

The short answer

The MX Master 4 is the more familiar choice: a comfortable shape, better scrolling and nothing new to learn. The MX Ergo S stays still while you steer with your thumb, so your arm barely moves, and it tilts to 20Β°, but a trackball takes practice and it's right-handed only.

Get the MX Master 4 if
  • β€”You want comfort without learning a new way to point.
  • β€”You scroll long documents and spreadsheets.
  • β€”You'd rather not learn a trackball.
