You can't input a specific DPI value, but a sensitivity slider allows for incremental adjustment between 200-4000 DPI. This program lets you set app-specific customizations, assign macros, tweak scrolling, enable/disable gestures, and receive low-battery notifications. Setting them up and managing all other features of the MX Master 3 is done via Logitech's Options software.

Pressing it opens the Task View in Windows by default, while pressing and swiping in any of the four directions gives access to as many shortcuts. It's why Logitech has given it the same machined steel treatment as the main scroll wheel, since both are expected to see plenty of use.Īnother layer of functionality is provided by the 'gesture' button located at the base of the thumb rest.

The latter feature, which might seem a bit extra at first, can prove invaluable for productivity workflows like navigating between lines of code or a design canvas, formatting documents, or just skimming through web pages. The uncluttered redesign makes for much easier operation of the two buttons and the horizontal scroll wheel over previous models. Logitech has also refined the Master's side profile by repositioning the two macro buttons that were previously stacked adjacent to the horizontal scroll wheel. It might seem over-engineered, but Logitech's decision to use magnets allows for quieter scrolling than traditional designs, and is meant to give improved feedback when rolling over content. The magnetic scroll wheel dynamically adjusts to ratchet or free scroll mode depending on the rolling force applied, though users can still manually switch between them by pressing the dedicated button behind it. A premium mouse at a premium price, the MX Master 3 makes full use of its rather large right-handed profile with a total of eight buttons on an ergonomically sculpted shape.īetween the primary clickers sits the infamous, tactile scroll wheel that's now made of machined steel and uses Logitech's MagSpeed electromagnetic tech for precise control when scrolling line-by-line or super-fast scrolling when in free-spinning mode. Logitech's impressive run with the MX Master series has inspired plenty of rivals, and the latest version, despite minute improvements over its predecessor, is still the one to beat.
