Logitech MX Master 3S Review (2026) — Derek's Honest Take
Our Verdict
Derek's daily driver for four years across three mouse generations. The 3S refinements are the ones that mattered.

Derek has used MX Master mice since the 2S in 2020. He upgraded to the 3 in 2021 and to the 3S in 2023. The upgrades were not necessary — the 2S and 3 worked correctly — but each iteration improved something real. The 3S added quiet clicks that Derek did not know he cared about until his partner mentioned the clicking during a conference call. He ordered the 3S the same day.
The Silent Click Upgrade
The MX Master 3S has silent clicking that is 90% quieter than the MX Master 3. In isolation this sounds like a minor feature. In practice, it removes the clicking from every call Derek takes, every quiet working session, and every moment where desk sounds were a background awareness. Derek mentions this to Kyle on every video call Kyle complains about background noise. Kyle is still using a $15 mouse.
The Scroll Wheel
The MagSpeed electromagnetic scroll wheel is the feature most people mention and Derek agrees it is correct. The wheel can switch between ratcheted click-per-line scrolling and free-spinning momentum scrolling. Derek uses free-spin for long documents and ratcheted for precision work. The switch is a single click on the wheel itself. After four years, the wheel mechanism works identically to day one.
Multi-Device and Battery
The 3S connects to up to three devices simultaneously and switches between them with a button on the bottom. Derek uses this between his work laptop and personal Mac. The switch takes approximately one second. Battery life is approximately 70 days per charge — Derek charges it once every two months and does not think about it otherwise.
