Logitech MX Master 4 vs Logitech MX Ergo S Wireless Trackball
Get the Logitech MX Master 4. Unless moving a mouse around hurts your wrist or shoulder, or your desk is small — then the MX Ergo S trackball.
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
The best trackball: you steer with your thumb, so your arm stays still. It tilts to 20°, clicks silently and lasts about four months per charge. US shops sell it as the MX Ergo S Plus, with an extra wedge.

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 20°, but a trackball takes practice and it's right-handed only.

- —You scroll long documents and spreadsheets.
