Cons

Our take
This is the MX Master for people who don't want to spend MX Master money. The community consensus is unusually strong for a budget pick — this one genuinely overdelivers.
If you spend 6+ hours a day at a desk, just buy this. It's the mouse that comes up in every single ergonomic thread, and for good reason — it's the rare product that actually delivers on its comfort promises.

Get the Logitech M720 Triathlon if you want budget performance. Get the Logitech MX Master 3S if you value overall more. Both are excellent choices in ergonomic mice.
