Logitech MX Master 4: A Two-Minute Review
The main new addition is a haptic touch panel for your thumb, and it provides physical bumps when activated and in use. While I’m happy to see it here, it’s actually far from the mouse’s best feature. That accolade goes to the MagSpeed scroll wheel, which automatically adjusts between precise clicks and freewheeling spinning. This is a wonderful inclusion.
Elsewhere, the indicator button is a helpful, customizable tool that can be adapted to your needs, as with many other buttons, with many presets and programmable adjustments that help you make the mouse your own. And it’s on the software side where the MXMaster 4 really beats the expense, with the awesome Logitech Flow making it a breeze to use the mouse across multiple computers and using the Options+ app serving as your customization hub.
It’s not a perfect mouse, though. It’s heavy and bulky, meaning it’s not ideal for travel or gaming, while the thumb wheel doesn’t feel anywhere near as responsive or premium as the Mag Speed wheel. Those points aside, though, there’s little else to be dissatisfied with.

The Logitech MX Master 4 is not a cheap mouse, either in terms of its price or its quality. Its cost is on the high side for a mouse, but it comes with a fleet of top tools and touches that enhance both your productivity and your overall computing experience. It’s not for everyone (especially gamers and those who want a lightweight mouse), but if you find yourself in its target audience, you’ll be very happy with it.
Logitech MX Master 4: Design
The picture 1 K 3
This mouse comes with the familiar sculpted design used by previous MX Master mice. It features a wide, arched body and cutout thumb area with a curved lip to rest your digit on. The mouse fits comfortably in your hand and should be suitable for all grip types, especially palms and claws.
This large form factor contributes to the weight of the mouse, which clocked in at 152 grams on my scales. It’s noticeably heavier, and whether that’s a good or bad thing really depends on your preferences. I’m used to featherweight mice (the 60g Logitech G ProX SuperLite 2 is my daily driver), so the MXMaster 4 took a bit of getting used to, and even after about two weeks of use, it misjudged its heft a touch. If you’re a frequent gamer and want something fast and light, this might not be ideal.
At the top are two large left and right click buttons. They come with incredibly soft, quiet clicks, which are satisfying to use and subtle enough not to annoy your co-workers. While the other mouse buttons aren’t loud by any means, it’s a shame they aren’t as unintuitive.
Located between the two main buttons is Logitech’s famous mag-speed scroll wheel. When it turns slowly and spins freely if you flick it with a little more force. It’s a great way to skim through websites and spreadsheets, and as small as it sounds, it’s one of the mouse’s best features.
Switching is automatic, but you can toggle one mode or the other using a button located just behind the wheel. Also note that you can click the scroll wheel, but there aren’t the kind of side-by-side clicks you might find on rival devices.
The MX Master 4’s real power features are mostly assigned to your thumb. The first is the horizontal scroll wheel, which is handy when you need to move side-to-side in an app like Microsoft Excel or when looking at a large image. Unfortunately, it lacks the ratchet/free spin capabilities of the Mag Speed wheel, and is quite cumbersome and imprecise to use. It’s also sharp and scratchy when turned, making it feel much cheaper than the rest of the mouse.
Below this wheel are three thumb buttons. The first two are grouped together, while the third stands slightly apart. The buttons aren’t particularly well-defined – there’s no difference between the first two – which makes them a little harder to disengage just by touch. The third is Logitech’s gesture button, which we’ll cover in the performance section, but note that all three can be customized to perform different functions.
The main part of the thumb rest is occupied by a faded indicator button, which is a new addition to the MX Master 4. It’s large and roomy, taking up almost the entire thumb rest area, and its textured surface makes it easy to grip. Pushing it brings up Logitech’s ring of actions, and a haptic bump whenever you mouse over one of the color icons. We’ll get into its features in more depth further down, but it’s a useful and thoughtful way to add more functionality to this part of the mouse.
On the underside is a quick switch button to move between connected PCs, allowing the MX Master 4 to connect to up to three computers at the same time (including Windows, macOS and Linux machines). There are also three black pads to help the mouse glide smoothly over surfaces.
Logitech MX Master 4: Performance
The first thing I want to cover in terms of performance is the mouse’s battery life, which is absolutely phenomenal. The Logitech Options+ app only measures the battery in 5% increments, but even so, it took more than 20 hours before I saw the first drop from 100% to 95%. After about 35 hours the mouse was still sitting pretty at 95%. Logitech rates it for 70 hours on a single charge, but it felt like it could last for decades.
The MX Master 4 isn’t a gaming mouse, but many people are likely to use it for work and play in their daily use. Unfortunately, its considerable weight means it’s not well-optimized for high-speed shooters The call of duty or other titles where agility and speed are required. Like slow play Baldur’s Gate 3 or Stardo Valley Didn’t present too many problems, though I still prefer a lighter mouse for gaming.
You get the same 8K polling rate as the MX Master 3s, which may be attractive to high-end pros looking for high sensitivity, but is probably low on the priority list for average users. What’s of more use to regular folk is the mouse’s ability to work on multiple tablets — Logitech says it will track correctly on “any surface,” and while I can’t 100% guarantee it’ll hold up to anything, it performed admirably on at least every surface material I tested it on (including mouse mats, wood, paper, fabric, and more). glass).
One of the MX Master 4’s key strengths is its customization, and much of that is achieved through the Logitech Options+ app. Here, you can change the functionality of the mouse’s seven physical features, including the five buttons and both wheels. Assigning new functions or creating your own is fast and intuitive.

The adjustability doesn’t end there. You can also tweak the strength of the new haptic feedback feature, thumb button press sensitivity, mouse pointer speed, scroll force and direction, and more. Don’t like how slow the thumb wheel moves or how difficult the taps of the haptic engine are? You can change all this in the software.
Options+ is also where you set up LogiFlow, which lets you use a mouse and software pointer for multiple computers and copy and paste files between them. It even works between Windows and macOS. Relocating a mouse from a Microsoft PC to a Mac and back feels both amazing and realistic, and it’s a fantastic weapon in your arsenal if you use more than one computer at once. It’s a little clunky — there’s a bit of a lag when moving from one computer to another, you can’t drag files directly across platforms, and copying and pasting objects was missing — but MXMaster 4 is better for its inclusion.
There’s a small gesture button tucked near where your thumb rests. The idea here is that you hold it, then move the mouse left, right, forward or backward to activate different gestures. By default, holding it and moving your mouse opens the Start menu in Windows, for example. These actions are customizable, with different presets available to try. This is a handy feature and can save you time, especially if you configure it in a way that fits your workflow.
Press in the dimpled thumb button and an “action ring” appears, eight buttons arranged in a wheel around your mouse pointer. These serve as quick shortcuts – change the volume, lock your computer, and more – and can be customized in the Logitech Options+ app. Mouse over each and you feel a solid haptic bump, though you can change the force in Logitech’s app.
The thumb button is a bit clunky and heavy to press, and the action ring can lag – I found that it didn’t always show up when I pressed the thumb button, for example. It also ended up being of limited utility during my time with the mouse, probably because I’m so entrenched in my working methods. But if you’re tired of keyboard shortcuts and want a faster way to work entirely with your mouse, this could be an attractive feature.
