Logitech MX Master 4 Review Roundup: What 7 Experts Say

Who it’s for

Logitech’s MX Master 4 for Business listing, covering the same mouse under a business SKU, calls it “our flagship mouse for business professionals” 1, and lists an 8K DPI Darkfield sensor, Quiet Click technology and haptic feedback as its core features. NotebookCheck frames it as “a clear recommendation for power users who spend a lot of time at the computer and want to optimize their workflows” 2. Engadget’s reviewer found it “supremely comfortable for medium and large hands,” but paired that with a direct warning that it isn’t built for lefties or small hands 3. RTINGS reaches the same conclusion about hand size independently, listing poor suitability for smaller hands as a drawback even while naming the MX Master 4 the best productivity mouse for most users 4. The horizontal thumb wheel pulls double duty for spreadsheet work and video-editing timelines, according to PCWorld 5, and NotebookCheck notes the haptic feedback is most useful with the Actions Ring and creative apps like Photoshop and Premiere Pro 2. Buyers coming from an older Logitech mouse rather than the immediate MX Master 3S get the clearest jump in features 6. Competitive gamers, left-handed users and anyone who wants onboard memory without companion software should look elsewhere 34.

What reviewers praise

Build quality of the Logitech MX Master 4 draws the most consistent praise. RTINGS calls it “an outstanding work mouse with superb build quality” 4, and PCWorld separately credits its ergonomics and construction alongside a scroll wheel with adjustable resistance 5. NotebookCheck’s review lists ergonomics and precision among its top strengths too 2.

The dual scroll wheels draw praise in four reviews 3754. Engadget lists high-quality, versatile scroll wheels among its pros 3, The Gadgeteer names the smooth scroll wheel as a strength 7, and PCWorld credits the adjustable resistance of the main wheel 5. RTINGS highlights the primary wheel’s ability to switch automatically or manually between a notched mode and free-spin scroll, alongside the gesture and haptic buttons as dedicated productivity features 4. PCWorld’s reviewer found the sensor tracks accurately on almost any surface, including glass, with immediate response 5.

No cited review lists battery life among its drawbacks; PCWorld, How-To Geek, The Gadgeteer and NotebookCheck each name it as a strength 5672. Logitech rates it at up to 70 days per charge 8. Console Creatures measured only about a 5% charge drop over three weeks of typical use 9. Logitech rates a one-minute charge at up to three hours of additional use, a figure NotebookCheck repeats, and the mouse can be used while charging 82; Console Creatures puts the same three hours at ten minutes of charging rather than one 9.

The new haptic Action button wins over the reviewers who use it: How-To Geek’s reviewer calls it “one small update that changed my entire workflow” after reprogramming it for macOS window management 6, and Console Creatures describes the haptic feedback as gimmicky but nice, wishing it extended further into browser use 9.

Common criticisms

Weight is the most repeated complaint about the Logitech MX Master 4. PCWorld describes the mouse as heavy and slightly sluggish when moving quickly 5, and NotebookCheck’s cons list is blunter still, simply calling it quite heavy 2. RTINGS measured a default weight of 151.8 g on its unit, slightly above Logitech’s stated 150 g spec 48.

Software dependency is another sore point. PCWorld flags a limited ability to create custom macros and says Logi Options is built around app-specific workflows rather than free custom shortcut chains 5. RTINGS adds that many features, including the gesture and haptic buttons, need background software running just to function 4.

Missing hardware conveniences come up across several reviews: Engadget lists no onboard memory and no storage compartment for the USB receiver among its cons 3, and RTINGS separately notes the lack of onboard memory means software is required to use any customized settings 4. Console Creatures’ only listed con for the mouse is the same missing dongle storage 9.

Price is a factor for some reviewers: How-To Geek’s sole con is that the MX Master 4 costs $20 more than the previous generation at launch 6, and Engadget separately calls it on the pricier side 3. PCWorld sums up its take plainly: “I’d like a bit more software flexibility and a lighter weight, but overall, Logitech has refined a classic into something excellent” 5.

Where reviewers disagree

Reviewers don’t agree on how much the extra weight matters in practice: PCWorld and NotebookCheck both treat it as a straightforward drawback 52, while Console Creatures lists the weight as a positive and cites 150 g against the 3S’s 141 g and says the difference is too slight to notice 9.

The Action button and the separate gesture button land differently depending on who tried them. How-To Geek credits the new Action button with changing its reviewer’s entire workflow after reprogramming it for macOS 6. PCWorld is cooler on the separate gesture button, calling it clever in theory but saying its reviewer rarely uses it because keyboard shortcuts are often faster 5. The Gadgeteer calls the Action button and Actions Ring cool but says its reviewer does not use them, relying on existing keyboard macros and Raycast instead 7.

Alternatives

The obvious comparison point is the MX Master 4’s own predecessor, the MX Master 3S. Engadget describes the MX Master 4 as sharing the 3S’s general shape, battery life and 8K DPI sensor, with the changes concentrated in the finish, size and haptic button 3. The Gadgeteer, which compared the two mice directly, found the differences too subtle to call it a redesign 7. The MX Master 4 launched $20 above the previous generation, so buyers who don’t need the haptic Action button can stay on an MX Master 3S for less 67.

For a cheaper, lighter alternative, RTINGS points to the Keychron M6, which shares a similar ergonomic shape and dual scroll wheels and offers free-scrolling at a much lower price, but has noticeably lower build quality and lacks the MX Master 4’s gesture and haptic buttons 4.
