Logitech MX Master 4: problems, parts and running costs
Checked: 2026-10-19
Summary
A right-handed wireless productivity mouse with an 8,000 DPI sensor, MagSpeed scroll wheel and a haptic feedback panel. Recurring issues are practical omissions in the box (no USB-C cable, no dongle storage), a right-handed shape that is too large for small hands, no onboard memory and haptics that cut battery life. There are no consumables; iFixit sells replacement batteries, so the mouse is serviceable. At $119.99 or below it is a strong buy; above $140 the case weakens.
Common problems and fixes
- No USB-C cable and no dongle storage in the box — the mouse ships without a USB-C cable and without anywhere to store the Logi Bolt receiver. [2][4]
- Right-handed only and too large for small hands — the shape is right-handed only, and Wirecutter’s small-handed testers found it uncomfortably large. [2][4]
- No onboard memory — DPI and button settings do not persist across computers or after uninstalling Logi Options+. [4]
- Default DPI of 1,000 is too low — Wirecutter’s tester preferred about 1,600 on both 27-inch and 14-inch screens, and changing it requires Logi Options+. [4]
- Haptics reduce battery life — Logitech warns that stronger haptics drain the battery faster; PCMag measured at least 70 hours per charge with haptics on versus a claim of up to 70 days. [2][4]
- Battery degrades over time — the internal battery is not user-swappable, unlike a mouse running on a replaceable AA cell. [4]
- Windows 10 cannot use Bluetooth — Windows 10 users are limited to the Logi Bolt receiver. [2]
- Native Windows 11 haptics need an OS update — requires a Windows 11 update from the end of March 2026 plus a firmware update through Options+. [1]
Parts and consumables
- Replacement battery (iFixit) — iFixit sells replacement batteries for the MX Master 4, which aids long-term serviceability. [4]
Yearly running cost
No subscription or consumable is reported. The only cost is charging a rechargeable mouse: Logitech claims up to 70 days per charge, and PCMag measured at least 70 hours per charge with haptics on. Not enough data for a yearly dollar figure. [2][4]
When it is a good buy
Price anchors: Logitech US store $119.99 with free shipping and 30-day returns (2026-10-19); about $114-120 at major US retailers including $114 at Best Buy and $120 at Walmart (Sep 2026); MSRP $119.00 per PCMag (Sep 2025). [1][4][2]
At $120 or below it is a strong buy for productivity work, and it is PCMag’s Editors’ Choice for best mouse for work. From $121-140 it is fair value; compare against the MX Master 3S, which is often discounted, and the Razer Pro Click V2, which PCMag rates 4.5 at a lower price. Above $140 the case weakens against those rivals. [2][4]
