Logitech MX Master 3chat_bubble_outlineFrom real comments

Ergonomics and productivity features win over long-term users. Commenters repeatedly describe the MX Master 3 as the best mouse they've used for office work, CAD, and spreadsheets, citing its shape, side buttons, thumb wheel, and configurable gestures. Several owners have used earlier MX models for years, even a decade, with some reporting relief from wrist strain and RSI. The horizontal scroll wheel and free-spin mode are called genuine productivity boosters for scrolling documents and diagrams.

Coating durability and left-click switches are common failure points. Multiple users report the rubber or plastic shell degrading, becoming sticky, melting, or discoloring within a year or two, with some suspecting planned obsolescence. Others describe the left-click button developing a double-click or dead-click fault after roughly a year of use, sometimes requiring disassembly, cleaning, or switch replacement to fix, which frustrates buyers given the mouse's price point.

Polling rate and Bluetooth performance frustrate precision-focused users. Several commenters call the 125Hz polling rate outdated and noticeably choppy on high refresh-rate screens or when compared to gaming mice, though others say it's a non-issue for non-gaming productivity work. Mac users in particular report lag, jitter, or disconnects over Bluetooth, sometimes fixed by using the USB dongle instead, along with complaints about missing onboard memory and no included charging cable.
