Your laptop mouse is in all probability something you either never think about or obsess over. Much like the world of laptop keyboards, discovering the proper PC peripherals can be fairly the rabbit gap to tumble down once you begin researching the choices.
You start to study why you might think about spending more than £100 on a mouse when you can get one for a tenner on Amazon.
Over the previous few years, Logitech has established itself as the entrance runner in ergonomic mice. Its flagship accent is the MX Master, which has gone through several iterations and has confirmed immensely well-liked thanks to its great design, long battery life, extra button for fast access to more options, and curler wheel.
I’ve been testing the new £119.99 MX Master 4 for a few weeks and am unsurprised that I love it. I’ve beforehand used the MX Master 2 and 3 (though not the earlier technology 3S), so I didn’t think the lineup needed much of a refresh.
How unsuitable I was, though the improve I want is not the one the MX Master 4 is marketed on.

The greatest change here is the new haptic button that sits where your proper thumb rests. Unfortunately, there is no left-handed model of the MX Master 4. This is a enormous oversight contemplating the vary’s persevering with recognition.
For the righties, as you press this new haptic space, you can really feel button-like suggestions from a vibration motor. On older fashions, you can push down for a bodily click on, which felt less intuitive.
But this new button does nothing without Logitech’s Logi Options+ software program. Once put in, urgent the button calls up what the firm calls the Action Ring, a software program overlay that pops up with a wheel of icons that you can customise. Holding down the button, you drag your cursor to the option you need to shortly access, such as commonly used apps or actions.

It’s intelligent, but you might not need it relying on your workflow. At launch, it supports apps such as Photoshop and Excel, and the overlay adapts if you are in these apps and lets you shortly carry out actions. You can also program it to carry out actions from AI apps such as Copilot and Perlexity, but it’s a massive no thanks from me on that entrance.
This works with Windows or macOS. Confusingly, there is a particular white Mac model of the mouse obtainable even though the common graphite model works completely properly on both platforms. A Logitech spokesperson advised me it primarily sells the white one ‘for Mac’ to appeal to an Apple viewers rather than the product having any particular {hardware} variations.
I was much more impressed with a less complicated improve. Although the MX Master 3S launched silent clicks, I didn’t use that model, so the silent left and proper buttons on the MX Master 4 blew me away. My older mice now appear to make a racket when I evaluate them to these buttons, which make only the faintest noise but still give first rate bodily suggestions. It’s a tiny high quality of life enchancment, but getting rid of the audible mouse click on is great for you and your workplace colleagues.

I also love the new, delicate textures on the high of the mouse. Where your palm rests now is coated in tiny microdots, which are designed to stop the materials carrying and changing into shiny and worn over time. The left and proper buttons are now an opaque plastic, which will hopefully imply less put on too.
Battery life is glorious. From totally charged, I used the mouse every weekday for 4 weeks and at the time of writing, it has 35 p.c left in the tank. That’s 20 days and 65 p.c used, so at this charge the mouse won’t make it to 70 days of use, which Logitech says is attainable, but if I only need to plug it in once a month or so that’s still fairly good.
The firm has also made the mouse more repairable than older variations, with screws on the backside and spare elements obtainable.
The MagSpeed Scroll Wheel is current and right, permitting you to scroll with conventional thunks or fully easily at the press of a button. You can scroll up to 1,000 strains per second, making this a good decide for the spreadsheet warrior and coders out there. It merely reacts fantastically to scrolls with precision and fluidity on Windows and Mac that cheaper mice lack. It actually is a great improve.
One factor price noting is that the 125Hz polling pace, which means the cursor can react 125 per second to motion, is not thought of fast enough for elite PC gaming.

You also can’t store the included USB-C receiver dongle in the physique of the mouse, making it straightforward to lose. I want connecting over Bluetooth, but the dongle presents longer vary and supposedly a more exact connection. It’s good to have both choices.
Who knew I could write so much about a laptop mouse, and one that prices a penny under £120 at that? If I had that quantity of money to spend on a mouse though, this one would be it. I don’t hate Apple’s flat Magic Mouse, but that accent is a design-first mouse with a flat type that you can’t charge while you’re utilizing it.
The MX Master 4 is the antithesis. It’s really fairly ugly and is unapologetically plastic, designed fully around consolation and utility. It’s costly, but it’ll last years if my older variations are anything to go by, and the new software program options and silent buttons are a great improve on your present mouse.
