Logitech MX Master 3S: what owners actually say
Owners consistently call it the best mouse they've used, but a recurring left-click switch failure around the 2-year mark overshadows an otherwise premium experience.
What owners complain about
- Left-click switch failure COMMON
Multiple owners report the left-click button becomes faulty or unusable after roughly 2–2.5 years. One user had it on both the Master 3 and the 3S; another had a warranty replacement develop the same issue. Owners feel the switches don't match the price point.
- Linux/Bluetooth reconnect delays SOME
On Linux, the mouse can take 5–10 seconds to register after a clean boot before it starts working. Some users solved this by switching to the linux-lts kernel. Suspend/sleep reconnection behavior is inconsistent.
- Scroll wheel unpredictability SOME
The MagSpeed scroll wheel behaves erratically if treated like a standard mechanical wheel. On macOS, owners need third-party software (Mos) alongside Logitech Options to get acceptable scrolling behavior. Users say you must learn to work with the design rather than against it.
- Thumb pain from weight and shape FEW
One owner developed thumb pain from lifting the mouse to re-centre it, attributing it to the shape and weight causing palm muscle spasms. Another commenter wishes for a lighter version.
- White version resists cleaning FEW
A long-term owner of the white model says it is very difficult to keep clean over time.
What owners love
- Best mouse they've ever used
Multiple long-term owners (2+ years, some using the MX Master line since 2012) call it the best mouse they've owned. Reliability and Bluetooth stability are highlighted alongside overall satisfaction.
- Ergonomic comfort for large hands
Owners with large hands specifically praise the fit. One user says it's the best mouse they've found for their hand size, and another notes it helps relieve discomfort from other mice or trackpads.
- Exceptional battery life
Owners report the battery lasting months at a time on a charge. The rated battery life is 70 days, which one commenter corrected from a reviewer who mistakenly said 70 hours.
- Thumb button for productivity
One owner specifically praises the thumb button as a 'life saver' for frequent screen captures and productivity workflows.
Surprising patterns
- Owners are 3D printing custom replacement shells for the MX Master 3/3S because original shell parts aren't available — one estimated removing the rubber slab from the top cover alone reduced total weight by 20%.
- The left-click switch failure appears systemic across the MX Master line (Master 3 and 3S both reported), with one owner going through a warranty replacement only to have the identical failure recur.
- The pointer reportedly becomes erratic and unstable as the battery gets low, which at least one owner noticed as a recurring pattern across two separate units.
WHO SHOULD SKIP IT
Left-handed users (it's right-handed only), competitive gamers wanting high polling rates and low weight, and Linux users who need reliable Bluetooth reconnection without kernel workarounds.
