Summary
The Logitech MX Anywhere 3S is a compact wireless productivity mouse aimed at users with smaller hands who need portability above all else. Reddit sentiment is generally positive for its intended use case — travel, multi-device switching, and all-day desk work — but tempered by a well-documented left-click failure issue that affects a meaningful number of users within 1–2 years. The Darkfield sensor is consistently praised for working on virtually any surface including glass, making it genuinely useful without a mousepad. It sits in an awkward value position at $70–100 depending on region, where many feel the hardware does not justify the price given the switch reliability concerns.
