Hardware · Video ReviewTerafied's review calls the 3S a quiet upgrade that may not justify leaving the MX Master 3. We agree — and still recommend the 3S as the first mouse most developers should buy if they own neither.
Benchlog archives and annotates public hardware reviews. The original video remains the property of its respective channel and rights holders.
Quiet clicks and MagSpeed scrolling still make the MX Master 3S the productivity mouse to beat. Upgrade from a 3 only if silence matters; buy fresh if you are still on a cheap office oval.

Written context that sits beside the video — what the numbers mean for a real build.
The MX Master line is the rare peripheral that shows up on designer desks and SRE laptops for the same reason: hours of cursor work without drama. The 3S iteration is not a redesign — it is quieter switches and a higher DPI ceiling on the same sculpted shell.
Terafied's video is blunt: if you already own an MX Master 3, the upgrade is incremental. That honesty is why we paired it. Our job is the software-desk framing — when the 3S is still the right cart item.
MagSpeed scrolling is the killer feature for logs, diffs, and long docs. Ratchet for line-by-line; free-spin for jumping a thousand lines of Kubernetes YAML without carpal theater.
Easy-Switch + Flow earn their keep on dual-machine desks (MacBook + Linux tower). Gesture button mapped to desktop switch or back/forward beats trackpad gymnastics mid-PR.
PullBuy the 3S if you have no Master. Keep the 3 if silence is not your bottleneck.
| Change | Worth it if… |
|---|---|
| Quiet Click | Open office / shared rooms / late calls |
| 8000 DPI ceiling | High-res / multi-monitor fine control |
| Same shape / wheel | You already love the 3 — muscle memory stays |
| Same street price band | Buying new: get 3S. Owning 3: usually keep it |
| If you… | Verdict |
|---|---|
| Ship software 8+ hours/day on a mouse | Buy 3S |
| Own MX Master 3 and like it | Skip — unless quiet clicks are required |
| Want a gaming + work hybrid | Look at G502 / lighter ergo hybrids |
| Are left-handed | Do not force this shell |
Paired with a QMK board and a single-cable dock, the MX Master 3S is still the mouse we hand to a new engineer on day one.
