Logitech MX Master 4: Two-minute review

(Image credit: Future)

Logitech’s MX Master is one of the best-known mice in the business, and the last iteration – the MX Master 3S – has long been seen as one of the best mice you can buy. That means the new MX Master 4 has big shoes to fill – and it doesn’t disappoint.

The main new addition is a haptic touch panel for your thumb, and this provides physical bumps when it’s 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. It’s a brilliant inclusion.

Elsewhere, the gesture button is a helpful, customizable tool that can be adapted to your needs, as can many of the other buttons, with a range of presets and programmable adjustments that help you make the mouse your own. And it’s on this software side where the MX Master 4 really excels, with the superb Logitech Flow making it a breeze to use the mouse across multiple computers and the Options+ app serving as your customization hub.

This is not a perfect mouse, though. It’s weighty and bulky, meaning it’s not ideal for travel or for gaming, while the thumb wheel doesn’t feel anywhere near as responsive or premium as the MagSpeed wheel. Those points aside, though, there’s very little else to be dissatisfied with.

Logitech MX Master 4: Price & availability

• How much does it cost? $119.99 / £119.99 / AU$199.95
• When is it available? Available now
• Where can you get it? Available globally

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 raft 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 likely be very happy with it.

Logitech MX Master 4: DesignImage 1 of 3

This mouse comes with the familiar sculpted design used by previous MX Master mice. That includes a wide, arched body and a cut-out thumb area with a curved lip for your digit to rest on. The mouse fits snugly in your hand and should be suitable for all grip types, particularly palm and claw.

That large form factor contributes to the mouse’s weight, which clocked in at 152g on my scales. It’s noticeably heavy, and whether that’s a good or bad thing really depends on your preferences. I’m used to featherweight mice (the 60g Logitech G Pro X Superlight 2 is my daily driver), so the MX Master 4 took a bit of getting used to, and even after almost two weeks of usage, it felt a touch imprecise due to its heft. That might not be ideal if you’re a frequent gamer and want something fast and light.

On the top are two large left- and right-click buttons. These come with incredibly soft, quiet clicks, which are both satisfying to use and subtle enough not to annoy your coworkers. While the mouse’s other buttons are by no means loud, it’s a shame that they aren’t quite so noiseless.

Nestled between the two main buttons is Logitech’s renowned MagSpeed scroll wheel. This ratchets when turned slowly and spins freely if you flick it with a bit more force. It’s a brilliant way to skim through websites and spreadsheets, and as small as it sounds, it’s one of the mouse’s best features.

The switching is automatic, but you can settle for one mode or the other using the button located just behind the wheel. Also note that you can click the scroll wheel in, but there are no side-to-side clicks of the type that you might find on rival devices.

The MX Master 4’s real power features are mostly assigned to your thumb. First up is the horizontal scroll wheel, which is handy if you need to pan side-to-side in an app like Microsoft Excel or when viewing a large image. Unfortunately, it lacks the ratchet/free spin abilities of the MagSpeed wheel, and it’s quite heavy and imprecise in use. It’s also loud 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 a short distance away. The buttons aren’t particularly well defined – there’s no gap between the first two – which makes them a little tricky to separate by touch alone. 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 dimpled gesture button, which is a new addition to the MX Master 4. This is large and spacious, taking up nearly the entire thumb rest area, and its textured surface makes it easy to grip. Pushing it in brings up Logitech’s Actions Ring, and there’s a haptic bump every time you mouse over one of the ring’s icons. We’ll get to its features in more depth further down, but it’s a useful and thoughtful way to add more functionality to this section of the mouse.

On the underside is a quick-switch button for moving between connected PCs, allowing the MX Master 4 to pair with up to three computers at once (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

(Image credit: Future)

The first thing I want to cover in terms of performance is the mouse’s battery life, which is absolutely phenomenal. The Logi Options+ app only measures battery in 5% increments, but even so, it took over 20 hours before I saw the first drop from 100% to 95%. After close to 35 hours the mouse was still sitting pretty at 95%. Logitech rates it for 70 hours on one charge, but it felt like it could go on for decades.

The MX Master 4 is not a gaming mouse, but plenty of people are likely to blend work and play throughout their daily usage. Unfortunately, its substantial weight means it’s not well optimized for fast-paced shooters like Call of Duty or other titles where agility and speed are required. Slower games like Baldur’s Gate 3 or Stardew Valley didn’t present many problems, although I still prefer a lighter mouse for gaming regardless.

You get the same 8K polling rate as the MX Master 3S, which might be attractive for top-end pros looking for high sensitivity, but is probably lower down the list of priorities for average users. What is likely to be more applicable to regular folk is the mouse’s ability to work on a variety of tabletops – Logitech says it’ll track properly on “any surface,” and while I can’t 100% guarantee it’ll stand up to anything it encounters, it at least performed admirably on every surface material I tested it on (including a mouse mat, wood, paper, fabric and glass).

One of the MX Master 4’s key strengths is its customizability, and most of this is achieved through the Logi Options+ app. Here, you can change the functionality of seven of the mouse’s physical features, including five buttons and both wheels. It’s quick and intuitive to assign new functions or create your own.

The adjustability doesn’t end there. You can also tweak the strength of the new haptic feedback feature, the press sensitivity of the thumb button, mouse pointer speed, scroll force and direction, and more. Don’t like how slowly the thumb wheel moves or how hard the haptic engine taps? You can change it all up in the software.

Options+ is also where you set up Logi Flow, which lets you use one mouse and software pointer for multiple computers and copy and paste files between them. It even works between Windows and macOS. Moving the mouse from a Microsoft PC onto a Mac and back again feels both wondrous and surreal, 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 slight bit of lag when going from one computer to another, you can’t drag files directly across platforms, and copying and pasting items was hit and miss – but the MX Master 4 is better for its inclusion.

Tucked away near your thumb’s resting spot is a small gesture button. The idea here is that you hold it down, then move the mouse left, right, forward or back to activate various gestures. By default, holding it and moving your mouse forward opens the Start menu in Windows, for example. These actions are customizable, with various presets available to try. It’s a handy feature and can save you time, particularly if you set it up in a way that suits your workflow.

Press in the dimpled thumb button and an “Actions Ring” appears, with eight buttons arranged in a wheel around your mouse pointer. These serve as quick shortcuts – change the volume, lock your PC, and more – and can be customized in the Logi Options+ app. Mouse over each one and you feel a solid haptic bump, although you can change the force in Logitech’s app.

The thumb button is a bit clunky and heavy to press, and the Actions Ring can be laggy – I found that it didn’t always appear when I pressed the thumb button, for example. It also ended up having limited utility during my time with the mouse, perhaps because I’m so ingrained in my ways of working. But if you’re tired of keyboard shortcuts and want a fast way of working solely with your mouse, it might be a tempting feature.

Razer Pro Click

Razer is best known for its gaming peripherals, but its Pro Click mouse is all about business.

Apple Magic Mouse 2

Apple’s Magic Mouse 2 is far from perfect, but it has one advantage that very few rivals can match: its entire top surface works as a gesture pad, letting you perform the same swipes that you’d use on one of Apple’s trackpads. It’s macOS-only, but if you want something that offers even better gesture control than the MX Master 4, it’s worth a look. View Deal

PNY microSD Express Card: review

The PNY microSD Express Card is one of the fastest Nintendo Switch 2 cards that I’ve tested.

In my benchmarks, the 256GB model achieved a staggering 712.42MB/s write speed - blowing past the competition and coming impressively close to the manufacturer’s claimed 750MB/s performance.

It also excels when it comes to read speed, actually achieving above the claimed 890MB/s with 893.74MB/s in my testing. This difference is likely all down to different conditions and equipment, but it’s safe to say that this card is quick. Its read speed is practically neck and neck with the licensed SanDisk microSD Express Card for Nintendo Switch 2 - a model that’s officially endorsed by Nintendo.

What does this all mean in practical terms? Well, the PNY MicroSD Express Card is fantastic to use with a Nintendo Switch 2. Internet providing, games download quickly and everything runs smoothly while you play. I tested the likes of Cyberpunk 2077: Ultimate Edition and Hitman World of Assassination - Signature Edition, two very demanding Nintendo Switch 2 games, and didn’t observe any noticeable performance decrease in either - be that missed frames, slow-to-load models, or increased load times.

(Image credit: Future)

Best of all, the 256GB PNY MicroSD Express Card is practically the same price as its major competition. At $59.99 / £59.99 / around AU$100, the leading write speed is a good reason to pick this card over the alternatives. This is the case for the warranty too, with PNY offering a five year or “limited lifetime warranty” in some regions.

This refers to the lifetime of the card (not you) and doesn’t cover you if PNY stops making them, but should otherwise see you through the life of the Nintendo Switch 2 at least - just make sure that you hang on to your proof of purchase and retail packaging in case you need to claim it.

PNY is also one of the few manufacturers offering a cheaper 128GB model, which goes for $44.99 / £39.99 (or even less in sales), allowing players with very modest storage needs to avoid paying more for storage that they don’t need.

There is a catch when you start looking at variants above 256GB, though. There’s a recently released 512GB model on the market that comes in at $119.99 / around £150, but seems to be very hard to find outside of the US right now. There’s no 1TB model yet either, leaving those with massive libraries better off with the competing Lexar Play Pro microSD Express Card instead.

Should I buy the PNY microSD Express Card?Buy it if...

You want high-end performance
The PNY microSD Express Card has the fastest write speed of any Nintendo Switch 2 card that I’ve tested. This is backed up by an excellent read speed, making it a good choice for those after a high performance card.

You’re after peace of mind
With its “lifetime” warranty, the PNY microSD Express Card should comfortably last you the entire life of the Nintendo Switch 2. This could be the first and last microSD Express Card that you buy.

Don't buy it if...

You need bigger storage capacities
The 512GB model appears to be quite hard to find outside of the US, and there’s no 1TB version yet. With this in mind, there are better options for those with big game libraries.

How I tested the PNY microSD Express Card

• Tested over a period of multiple weeks
• Compared to other microSD Express cards
• Measured using standardized benchmark tests

I tested the PNY microSD Express Card alongside multiple other microSD Express units over a period of multiple weeks. During that time I used the card with my personal Nintendo Switch 2, evaluating its performance across a range of the best Nintendo Switch 2 games.

To obtain comparison data, I benchmarked the card against the competition in a series of standardized tests. I measured the sequential read and write speed of each card using a standardized benchmark via CrystalDiskMark in its default flash memory settings.

To do this, I relied on the Lexar Play Pro MicroSD Express Card Reader, which has an active cooling fan.
