The MX Master 4 carries a reputation that very few computer accessories ever get to inherit. There is a reason creators like Marques Brownlee, Ali Abdaal, Casey Neistat, Austin Evans, and MrWhoseTheBoss have all, at different points in their careers, relied on the MX Master. That trust was built through long workdays, reliable tracking, and a level of customisation that adapts easily to different workflows.
I have wanted an MX Master on my desk for a long time, so when the opportunity to review the MX Master 4 came up, I took it without hesitation. This is not a gaming mouse, and it does not attempt to be one. My Logitech G304 still makes far more sense in that role. But for productivity, comfort, and extended all-day use, the MX Master 4, like the models before it, operates on a different level.
Rather than pushing for a dramatic redesign, Logitech has taken a measured path. The MX Master 4 looks familiar at first glance, but the changes start to matter once it becomes part of your daily routine.
With an official price of ₹15,000 and online pricing closer to ₹12,000, it sits firmly in premium territory. The question, then, is straightforward: after wanting one for so long, is this finally the MX Master I would buy myself?
Anyone coming from an older MX Master will feel right at home with the MX Master 4 almost instantly. The hand position, the overall posture, and the way the mouse fills your palm are all familiar. Logitech has not attempted to rework the fundamentals here, and visually it still sits very close to the MX Master 3S. That sense of continuity is deliberate. The real changes reveal themselves only after days of regular use, where the MX Master 4 starts to feel more polished and better thought through.
The mouse is offered in Graphite and Pale Grey, with a dedicated Mac variant available in White Silver. Colour options aside, the biggest improvement this generation comes down to materials. The rubberised finish on the MX Master 3S was one of its weakest points. It felt premium initially, but it did not age gracefully. Dust, skin oils, and everyday grime clung to it easily, and extended use often resulted in uneven wear and glossy patches that made the mouse feel prematurely worn.
That issue has been addressed decisively. The MX Master 4 switches to a higher-grade plastic across most of its surface. It still feels soft and pleasant in the hand, but without the tacky, dirt-loving behaviour of the earlier coating. Rubber has been restricted to the left and right wings, where grip is genuinely useful. In everyday use, this change makes the mouse feel cleaner, more durable, and far easier to maintain.
The left wing doubles as a thumb rest and now integrates the Actions Ring button. This is also where the haptic feedback is delivered. In use, the placement feels natural and intuitive. The button sits exactly where the thumb expects it to be, and I rarely needed to adjust my grip to reach it.
Logitech has also refined the main click area. The buttons are marginally larger, the loop around the scroll wheel has been removed, and the odd plastic extension on the right-click button from the MX Master 3S is no longer present. These are small tweaks individually, but together they give the mouse a cleaner and more cohesive look.
Click noise remains minimal. Like previous MX Master models, the MX Master 4 uses heavily dampened switches. There is very little audible feedback, and that is clearly intentional. Logitech has tuned this mouse for offices, shared workspaces, and long professional sessions where constant clicking can quickly become irritating. It may not satisfy those who enjoy pronounced tactile feedback, but it makes the mouse easy to live with for hours on end.
Scrolling continues to be a highlight. Both the MagSpeed main wheel and the thumb scroll wheel are aluminium, and both feel premium. The MagSpeed wheel remains exceptional. It offers precise, stepped scrolling when control matters, and seamlessly switches to free-spin mode at the press of a button. Even better, it adapts automatically to speed. Fast flicks glide freely, while slower movements return to controlled scrolling without any manual input.
The thumb wheel, while functional, still lags behind the MagSpeed wheel in feel. It is not as smooth, and the lack of a click limits its usefulness. Considering the mouse already offers eight programmable buttons, this feels like a missed opportunity to expand functionality further.
Below the thumb wheel sits the redesigned gesture button. Its new position makes it easier to press intentionally, and it feels more reliable during repeated use.
Despite not being marketed as a dedicated ergonomic mouse, the MX Master 4 is among the most comfortable work mice I have used. I have larger hands, and the shape fits exceptionally well. Long work sessions never caused fatigue or discomfort. It is still disappointing, though, that a left-handed version remains absent.
This is also not a mouse built for constant lifting or fast flicks, which makes gaming a poor fit. The grip does not encourage aggressive movements, and the Actions Ring button can be triggered unintentionally if you hold the mouse tightly. At 150 grams, it is also relatively heavy. By comparison, my Logitech G304 comes in at 99 grams with an AA battery.
That weight works against it in games, but becomes an asset in creative software. In tools like Photoshop and InDesign, the mouse feels planted and controlled, encouraging slower, more deliberate movements.
There is also a small nod to sustainability. The MX Master 4 is more serviceable, with exposed screws that should allow battery replacement in the future. While this has been possible in certain regions before, sourcing official replacement batteries in India remains difficult unless you are willing to venture into unreliable territory.
In terms of connectivity, the MX Master 4 gives you two clear options. You can use Logitech’s Bolt receiver, or go completely dongle-free with Bluetooth 5.1 Low Energy. I genuinely like having both, mainly because I switch between different work setups fairly often.
You can pair the mouse with up to three devices, and switching between them using the button on the bottom is quick and straightforward. Moving between my laptop and desktop felt fast and mostly seamless in day-to-day use.
Logitech says it has improved the internal antenna design and claims a wireless range of up to 10 metres. From my testing, that claim mostly holds up. As long as there were no major obstacles in the way, the connection stayed stable even when I moved a decent distance away from my desk.
For tracking, the MX Master 4 uses Logitech’s Darkfield high-precision sensor, and it has been rock solid for me. I tested it on a polished wooden desk, a regular sheet of paper, and even on glass. Tracking stayed consistent across all of them, including glass, which is still something many mice struggle with.
The DPI range goes from 200 all the way up to 8,000, and you can adjust it in fine 50-DPI steps. That level of control is genuinely useful if you care about dialing in pointer speed exactly the way you like it.
The weak point here is the polling rate. Whether you use the Bolt receiver or Bluetooth, it is capped at 125Hz. That feels disappointing at this price, especially when even basic wireless mice bundled with budget keyboard combos run at the same rate.
Connectivity itself is simple enough, but the experience of the mouse is incomplete without the Logi Options+ software. Until I installed the software, even basic things like the back and forward buttons did not work. Once everything is set up, though, the mouse finally delivers what you are paying for.
Logi Options+ is, without question, the most polished customisation software I have used from any peripheral brand so far. Even large PC makers like Dell, HP, and Asus could learn a thing or two from it. The interface is clean, the setup process is easy to follow, and nothing feels confusing or unnecessarily buried. From a pure design and usability perspective, Logitech has done this part really well.
However, I have a few issues, with the first and foremost being, that you need Logi Options+ in the first place. Without the software installed, a large chunk of what you are paying ₹12,000 to ₹15,000 for simply does not function. Even basic buttons like back and forward are useless until the app is up and running.
Logitech positions the MX Master 4 as a productivity mouse for professional and corporate users. In that context, setup at work should be painless. In reality, it is anything but. On most office machines, installing third-party software like Logi Options+ is painfully convoluted thanks to enterprise level security.
Even with admin access on my work system, I had to get the IT team involved to adjust permissions before the software would behave properly. On top of that, the app asking for keystroke access immediately raised concerns. I had to explain why that permission was required, which is not a great conversation to have in a corporate environment.
A potential workaround would be setting the mouse up on another system and then using it at work. That is not an option here. The MX Master 4 has no onboard memory, so none of the customisations carry over. You have to use the Logi Options+ app, and have it run in the background.
On my personal MacBook, though, the entire setup took under three minutes and worked flawlessly.
Once everything is in place, the experience is excellent. You get to set workflow-specific shortcuts, and profiles, like I did for Photoshop and Lightroom, which made my life a lot easier.
The MX Master 4 introduces two features that actually move the series forward in a meaningful way: the new haptic feedback system and the dedicated Action Ring button. These are not minor tweaks or background additions. They directly change how the mouse feels and how quickly you can get work done.
Starting with haptics, the feedback is stronger than I expected from a mouse that still looks this understated. Logitech gives you four intensity levels to choose from: subtle, low, medium, and high. I left mine on low, and even that felt more than enough for everyday use. Anything higher quickly starts to feel excessive.
The idea behind the haptics is simple. The mouse gives you a small physical confirmation when an action is completed. It is not meant to grab your attention or pull focus, but to reinforce what you are already doing. Once you get used to it, it starts to feel surprisingly natural.
A good example is layer alignment in Adobe Photoshop. Normally, you rely entirely on visual cues to know when a layer snaps perfectly into place. With the MX Master 4, I also got a subtle haptic nudge the moment alignment was complete. It sounds trivial, but during detailed edits, that extra confirmation genuinely helped, especially when making very fine adjustments.
You get similar feedback when using the Action Ring, Smart Actions, and gesture shortcuts. The haptics also kick in when switching between desktops or workspaces, which makes those transitions feel intentional rather than something you triggered by accident.
The other big addition is the Action Ring itself. While Action Rings technically came to the MX Master 3S through a software update, the MX Master 4 is the first model to support them properly with a dedicated hardware button. That distinction matters in daily use.
Pressing the Action Ring button brings up a circular menu of actions that changes depending on the app you are using. These actions are essentially macros tied to shortcuts, but the way they are presented makes them quick and intuitive to access. Logitech claims this can save up to 33 percent of working time and reduce mouse movement by 67 percent. I did not measure those numbers, but while editing photos in Adobe Lightroom and Photoshop for this review, my workflow did feel noticeably faster and more fluid.
Inside Logi Options+, you can also create multiple profiles within the same app. For example, you can set up separate Photoshop profiles for photo retouching and for vector or path-based work, each with its own shortcuts. Similar setups work well in Lightroom, DaVinci Resolve, and most other creative applications.
Rounding things out are familiar features like Easy Switch for managing three connected devices through the software, continued Action Ring integration, and Logi Flow, which lets you drag files, images, and text between two computers simply by moving your cursor across screens.
The MX Master 4 has a 650mAh battery, with Logitech claiming up to 70 days of use. I am inclined to believe that, because after a week of heavy use, my unit only dropped from 100 to 90 percent. Charging happens over USB-C, and a minute or two easily gets you through a full workday, without any range anxiety either.
Spending time with the Logitech MX Master 4 as my work mouse made its priorities obvious. This is a mouse designed around long hours at a desk, not something meant to impress quickly. Comfort continues to be the core strength.
The material changes make a difference in daily use, the MagSpeed scroll wheel remains unmatched, and the mouse feels planted and predictable during fine, detail oriented work. The addition of haptic feedback and the hardware backed Action Ring button also deserves mention. What felt unnecessary at first gradually became helpful.
There are compromises that cannot be ignored. The weight alone makes gaming unrealistic, the 125Hz polling rate feels embarrassingly low for a mouse at this price, and the thumb scroll wheel still falls short of the main wheel in feel and precision. I kept wishing there was a way to make it handle gaming duties, but that option is not there.
Software remains another concern. Logi Options+ is polished, but the reliance on it is frustrating. Without the software running, several features stop working, which becomes a problem in restricted office environments.
So would I still buy it, especially now that the MX Master 3S sells for much less? Yes. The older model had durability issues over time, and the MX Master 4 earns its place on my desk today.
