Whether the premium ergonomic mouse is worth the upgrade over a standard wireless mouse — a research-based evaluation weighed against its price tag.

The MX Master 3S sits at the top of Logitech's mouse lineup, and across published reviews and sustained owner feedback most of that reputation holds up — the scroll wheel and shape are consistently credited with changing how a full workday of clicking and scrolling feels, though it's a meaningful step up in price from a basic wireless mouse.
The Scroll Wheel Is the Real Upgrade
The MagSpeed wheel free-spins for fast scrolling through long documents or spreadsheets, then switches to a ratcheted click-scroll for precise line-by-line movement — automatically, based on how fast you spin it. This sounds like a minor feature until you're regularly moving through long spreadsheets, where it saves real time and hand fatigue.
Shape and Ergonomics
The sculpted shape supports a relaxed hand position better than a flat standard mouse, though it's not as aggressive an ergonomic angle as a fully vertical mouse. It's a reasonable middle ground for people who want some ergonomic benefit without the adjustment period a vertical mouse requires.
What We Liked
- +MagSpeed scroll wheel is genuinely faster for long documents and spreadsheets
- +Ergonomic shape reduces wrist strain compared to a flat standard mouse
- +Excellent tracking on glass and other surfaces most mice struggle with
- +App-based customization for gestures and per-application shortcuts
Where It Falls Short
- –Premium price relative to mice with similar core functionality
- –The customization software is more than most people will ever use
- –Right-hand-only shape, no left-handed version

The Verdict
Worth it if you spend significant time in spreadsheets or long documents — the scroll wheel alone justifies the price for that use case. If wrist strain is your primary concern rather than scrolling speed, a dedicated vertical mouse may serve you better.
