The answer — one pick, priced
Get the
Logitech MX Anywhere 3S
right at your $80 cap
The pick when the hand is small or unknown — the same 8K Darkfield sensor and MagSpeed wheel as the MX Master, in a 95 g, 100.5 mm body that also travels.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
It is small on purpose. At 100.5 mm and 95 g it is built for hands under about 17 cm and a claw grip — a big palm-grip hand will cramp on it all day. And the $79.99 buys the Pale Grey unit specifically; Graphite and Rose are separate SKUs at their own prices.
Dealbreaker? Runner-up №1 is the full-size palm shape ↓

Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Logitech MX Anywhere 3S is right for you
It avoids every trap below — and for any hand size, under $80, it is the pick because it delivers:
The dongle that will not pair
Logitech's Logi Bolt receivers are not cross-compatible with the older Unifying dongles — a drawer full of Unifying receivers pairs zero of the current MX and Signature mice. Check what is in the box, and keep a USB port free.
DPI is a decoy
Above about 4,000 DPI nothing improves for office work — the 30K and 26K sensors here matter only for multi-monitor or precision design work. Judge the scroll wheel instead; free-spin, tilt and a thumb wheel are what you actually use all day.
The older flagship now costs more
The MX Master 3S Standard Edition lists at $125.79 — above the newer MX Master 4 at $119.99, so the old "buy the 3S to save money" advice is dead. The Razer's $56.60 is a late-July promo that has traded as high as $99.99 this year. Check live prices before buying either.
