Which one to pick

Take the Logitech Ergo M575S

Leads on Value and Ease of use.

  • A desk with no room for a mouse to travel
  • Shoulder or forearm strain that comes from arm movement rather than rotation
  • You would rather clean a ball than remember to charge something

Take the Logitech MX Master 3S

Leads on Performance, Durability and Design.

  • Spreadsheets and long documents, where the free-spinning wheel earns its keep
  • Three computers and one mouse
  • You share a room and the old model's click was too loud

What each one gets wrong

Logitech Ergo M575S

  • Pixel work, where dragging small handles stays harder than it is with a mouse
  • Wiping the bearings every few weeks will annoy you
  • You switch between three machines and want one button to do it

Logitech MX Master 3S

  • Small hands — this is a large, high-backed shape
  • You want a symmetrical shape for left-handed use
