Logitech MX Anywhere 3S

The middle-click problem

This is the one reliability signal owners keep coming back to. In r/logitech, a November 2024 owner found a brand-new 3S registered a middle click only when pressed abnormally hard, which broke browser new-tab habits; Logitech support replied that firm, normal clicking should work and suggested cleaning. Follow-ups in the same thread describe two more new 3S units missing many middle clicks, and another replacement with the wheel rubbing the shell. A different owner reported both an Anywhere 3 and a 3S needing hard middle clicks after about eight months each. Nobody has published a failure rate, so treat this as a known annoyance rather than a proven defect — but test the wheel click inside the return window.

Not every scroll problem is hardware. A Logitech representative’s August 2026 post documents Options+ 2.6 causing smooth-scroll faults on the MX Ergo, MX Master 3S and M650 — the 3S is not on the list — with the 2.7 update rolled out by September 7, 2026.

Battery, polling and the dongle question

Logitech rates the built-in 500 mAh cell at up to 70 days per charge, with about three hours of use from a one-minute charge and a full recharge near two hours; that figure assumes ordinary office use, not round-the-clock motion. The energy math is trivial: a 500 mAh cell at 3.7 V stores about 1.85 Wh, so one charge every 70 days is roughly 9.6 Wh a year, and doubling for charging losses gives about 0.0192 kWh from the wall — around $0.005 a year at $0.25 per kWh. That is arithmetic, not a measured utility bill.

The USB-C port charges only; there is no wired data mode, so a cable alone never makes this a wired mouse. If you want a dongle, the Logi Bolt USB receiver is $14.99 at Logitech US and is not in the consumer box; the Unifying receiver from the MX Anywhere 3 will not pair. An optional travel case is $22.99.

Polling is the other spec that matters day to day. RTINGS measured a 125 Hz maximum, against 1000 Hz on mainstream gaming mice, so cursor motion on a 165 or 240 Hz display will feel less uniform. A July 2026 owner described pointer motion like 20–30 FPS on two different 3S units across Bolt and Bluetooth; the low report rate explains the ceiling but does not prove the stutter is inherent.

Warranty and support

Logitech’s limited hardware warranty covers manufacturing defects for the original purchaser, usually in the country of purchase. Two years is stated on non-US consumer pages and on the US business SKU; the US consumer page shows no clear term, so check the box or ask support before assuming coverage. Support asks for model, serial number and proof of purchase, and an RMA before you ship anything back. One exact-3S owner got a support offer to investigate a left-click failure in July 2026, with no public outcome. Logitech’s support page lists no spare parts for this mouse; a 2026 iFixit guide shows the business model’s battery can be swapped with specialist tools, but it does not cover the consumer SKU.

Is it worth it?

At $69.99 from Logitech US (promotion through November 1, 2026) it is easy to recommend for travel and multi-device work; at the $89.99 list price, which is also where Best Buy sits, the larger MX Master 4 at $119.99 or the Signature M650 at $39.99 are the comparisons worth making. The M720 Triathlon at $44.99 regular is the pick if you want a palm-filling shape on replaceable AA batteries. If you open hundreds of background tabs a day, the middle-click reports are a real reason to try before you buy.

Which model this is

This page covers the consumer MX Anywhere 3S, black SKU 910-006928. The MX Anywhere 3S for Business (910-006956) is a different SKU with a bundled receiver and enterprise support terms. The older MX Anywhere 3 and the full-size MX Master 3S are not equivalent, and Unifying receivers from the 3 will not pair with the 3S.
