Logitech MX Master 3S Review: Redefining Productivity in 2025
The Logitech MX Master series has long been a favorite among professionals and power users. With the MX Master 3S, Logitech aims to push the boundaries of what a productivity mouse can do. After three months of extensive testing across various devices and workflows, here's our in-depth review of this premium peripheral.
Design and Ergonomics: Comfort Meets Functionality
Refined Ergonomics
The MX Master 3S builds on its predecessor's design with subtle refinements. The contoured shape fits naturally in the hand, supporting various grip styles:
- Palm grip: Excellent support for medium to large hands
- Claw grip: Comfortable, with easy access to all buttons
- Fingertip grip: Possible, but less ideal due to the mouse's size
The textured rubber coating provides a secure grip, even during long work sessions. However, it's worth noting that after extended use, the coating can show signs of wear and may accumulate oils from your hand.
Button Layout and Accessibility
- Primary buttons: Responsive with a satisfying click
- Thumb rest: Integrated gesture button for customizable actions
- Side buttons: Easily accessible, with good tactile feedback
- Scroll wheels:
- Main wheel: MagSpeed electromagnetic scrolling
- Thumb wheel: Horizontal scrolling and customizable functions

At 141g, the MX Master 3S is on the heavier side. This weight contributes to a premium feel but may require an adjustment period for users accustomed to lighter mice.
