What Is the Logitech MX Master 3S?
The logitech mx master 3s is a high-performance wireless mouse designed primarily for productivity. Logitech introduced it as an updated version of the MX Master 3, adding a higher-resolution sensor and quieter clicking while retaining the distinctive ergonomic shape and scrolling system.
The mouse uses Logitech’s Darkfield high-precision tracking technology and supports sensitivity from 200 to 8,000 DPI in 50 DPI increments. Logitech says the sensor can track on virtually any surface, including glass with a minimum thickness of 4 mm.
Unlike lightweight gaming mice, this is a substantial mouse built around comfort, control, and functionality. Its 141-gram weight and large ergonomic body make it feel stable on a desk, although people who prefer very lightweight mice may find it heavy.
The logitech mx master 3s also provides seven programmable controls, a thumb wheel, gesture button, and SmartShift scrolling. These features make it possible to configure different workflows for applications such as Photoshop, Premiere Pro, Chrome, Word, Excel, and other supported software.

These specifications are based on Logitech’s current product documentation.
One important point is that the standard consumer version and business version can differ in included connectivity options and packaging. Buyers should check the exact model before ordering.
Design and Ergonomics
The shape is one of the biggest reasons people choose the logitech mx master 3s.
It has a pronounced ergonomic profile designed for a right-handed grip. Your thumb rests on a dedicated thumb area containing additional controls, while the main buttons and scroll wheel are positioned for conventional palm or relaxed claw-style use.
The body is relatively large compared with compact travel mice. That can be an advantage for users with medium or large hands because the palm has more support during long working sessions.
However, the shape is not universal. Left-handed users cannot take advantage of the mouse’s ergonomic design in the same way because it is specifically shaped for right-handed use.
At 141 grams, the mouse is also much heavier than many modern gaming mice. This is intentional: the additional weight and broad shape contribute to a controlled, planted feeling when navigating large screens or performing precise office and creative work.
RTINGS’ testing describes the MX Master 3S as retaining the ergonomic shape and productivity-focused feature set of the previous generation while adding quieter clicks and a wider CPI range.
8,000 DPI Darkfield Sensor
The logitech mx master 3s uses an 8,000 DPI Darkfield sensor, which represents a major improvement over the older MX Master 3.
DPI, or dots per inch, describes how sensitive the mouse is to physical movement. Higher DPI settings can move the cursor farther with less physical movement, although maximum DPI does not automatically mean a better mouse for every user.
For everyday office work, many users will never need the full 8,000 DPI setting. Its importance becomes more apparent when working with high-resolution displays or large desktop setups where precise cursor movement and quick navigation are both useful.
One of the unusual features is the ability to track on glass. Logitech specifies a minimum glass thickness of 4 mm for this capability.
The sensor can be configured through Logi Options+, allowing users to adjust tracking sensitivity according to their monitor setup and workflow.
MagSpeed Scrolling and Controls
The MagSpeed electromagnetic scroll wheel is another defining feature of the logitech mx master 3s.
Instead of relying on a conventional mechanical scrolling mechanism, the wheel uses electromagnetic technology to provide controlled and fast scrolling. Logitech states that it can scroll at speeds of up to 1,000 lines per second while maintaining enough precision to stop at individual pixels.
The SmartShift feature allows the wheel to switch between precise scrolling and rapid free-spinning behaviour.
This is particularly useful when navigating long webpages, spreadsheets, documents, timelines, or large design projects. A quick spin can move through large amounts of content, while slower movement provides more control.
The mouse also includes a horizontal thumb wheel. This can be useful for moving sideways through spreadsheets or timelines without relying exclusively on keyboard shortcuts.
There are also back and forward buttons plus a gesture button. All of these controls can be configured through Logitech’s software.
Logitech Options+ Software
Hardware is only part of the logitech mx master 3s experience. A major part of its functionality comes from Logi Options+.
Logitech’s software allows users to customise buttons, adjust pointer sensitivity, configure application-specific actions, and manage supported workflows. Logitech specifically lists applications including Adobe Photoshop, Adobe Premiere Pro, Final Cut Pro, Chrome, Safari, Zoom, Microsoft Teams, Word, Excel, PowerPoint, and Edge among its supported customisation environments.
This means the same physical button can perform different actions depending on the application being used.
For example, a button could be configured for a navigation function in a browser and assigned a different shortcut in Photoshop. This can reduce the need to memorise keyboard shortcuts for every application.
Logi Options+ also supports Smart Actions, which Logitech describes as a way to automate sequences of actions.
Multi-Device Connectivity and Flow
Another major advantage of the logitech mx master 3s is its ability to work across multiple devices.
The mouse supports Bluetooth Low Energy and Logitech’s Logi Bolt wireless receiver, depending on the version and package. Logitech lists a wireless operating range of up to 10 metres, although actual range can vary depending on the environment and computer setup.
This makes the mouse useful for people who regularly switch between a desktop, laptop, or other compatible computers.
Logitech’s Flow feature goes further by allowing users to move the pointer between computers and transfer certain types of content between supported systems. This can be particularly useful for people who use separate machines for work and personal tasks.
The experience is most useful when several computers are regularly used at the same desk. If you only own one computer, this feature may not matter much.
Battery Life and Charging
The logitech mx master 3s contains a rechargeable 500 mAh Li-Po battery and charges through USB-C. Logitech’s business documentation lists up to 70 days of battery life on a full charge under its stated conditions.
Actual battery life depends on usage and other factors, so the advertised figure should not be interpreted as a guaranteed number of days for every user.
USB-C charging is convenient because it uses the same general connector found on many modern laptops, phones, tablets, and accessories.
One practical benefit is that the mouse does not require disposable AA or AAA batteries. That makes charging straightforward and avoids the need to keep spare batteries around.
Logitech MX Master 3S for Creative Work
For designers and content creators, the logitech mx master 3s can be more useful than a basic office mouse because of its additional controls.
Graphic designers working in Photoshop or Illustrator-style workflows can assign frequently used actions to the side buttons, thumb wheel, or gesture button. Video editors can similarly benefit from horizontal navigation when working with timelines.
It is also useful for people who regularly switch between creative software, browsers, documents, and communication applications.
The important limitation is that it is still a productivity mouse rather than a specialised drawing device. Someone who needs a pen for detailed illustration will need a graphics tablet or pen display instead.
The mouse is best understood as a tool for navigating and controlling creative software rather than replacing specialised creative hardware.
Logitech MX Master 3S vs MX Master 4
The biggest question in 2026 is whether the logitech mx master 3s still makes sense now that Logitech sells the MX Master 4.
Logitech’s current UK store lists the MX Master 4 at £119.99, while the MX Master 3S is currently listed at a discounted price below its £89.99 regular price. Logitech’s US store currently lists the MX Master 3S at $89.99, with the displayed page showing a $99.99 regular price. Prices can change depending on promotions and region.
The MX Master 4 introduces newer hardware and features, including haptic feedback and deeper integration with Logitech’s current productivity ecosystem. That makes it the newer generation.
However, the existence of the newer model does not make the 3S unusable. The 3S still provides 8,000 DPI tracking, MagSpeed scrolling, customisable controls, multi-device connectivity, and Logi Options+ support.
For buyers finding the 3S at a substantially lower price, the older model can therefore remain an interesting option. The decision mainly comes down to price difference and whether the newer MX Master 4 features matter to you.

Who Should Buy the MX Master 3S?
The logitech mx master 3s is particularly suited to office professionals, programmers, designers, video editors, students, researchers, and anyone who spends many hours navigating documents and applications.
It is also a good match for people who frequently work with spreadsheets or large documents because the horizontal thumb wheel and fast MagSpeed scrolling can reduce repetitive scrolling.
Creative professionals may appreciate the programmable controls and application-specific settings.
On the other hand, gamers looking for an extremely lightweight mouse, high polling rates, or gaming-specific features should look at gaming-focused products instead.
Likewise, people who travel frequently may prefer a smaller mouse. The 3S is portable enough to carry in a laptop bag, but its larger ergonomic body and 141-gram weight are not designed around ultra-portability.
Is the MX Master 3S Worth Buying in 2026?
The logitech mx master 3s remains technically capable in 2026, but its value depends heavily on its current selling price.
The introduction of the MX Master 4 changes the buying equation. Buyers should compare the actual street price of both models rather than automatically choosing the newer mouse.
If the 3S is significantly discounted, its 8,000 DPI sensor, MagSpeed wheel, customisation options, and ergonomic design still make it a capable productivity mouse. If the price gap between generations is small, the newer model deserves consideration because it adds newer hardware and features.
For existing 3S owners, there is also little reason to upgrade purely because a newer model exists. If your current mouse works well and its features meet your needs, the productivity benefits of the newer generation may not justify replacing it.
