Logitech MX Master 3S Performance Wireless Mouse
design
There’s a classy simplicity to the Logitech MX Master 3S, largely monotone except for a couple of metal accent wheels, the MX Master 3S fades into the office scenery and doesn’t draw attention to itself. If you do let it catch your eye there’s a lot to enjoy though, with a handful of subtle design choices that make it really quite pleasant overall. Sweeping lines are the order of the day here and regardless of whether you opt for the Pale Gray or Graphite variant you’re left with a properly grown up looking mouse.
You’ll need to be right-handed to enjoy the Logitech MX Master 3S as the ergonomic shape and oversized thumb rest are entirely geared in this direction. There’s no left-handed variant, which is a shame, but for righties it’s a large and noticeably comfortable mouse. I’m naturally more of a palm grip person anyway so I felt right at home with the MX Master 3S but the overall shape pulls you into this grip naturally.
It’s a similar profile to the Logitech G502 X Plus gaming mouse, just with fewer sharp edges and definitely no RGB. It’s worth noting the size of the MX Master 3S because it’s surprisingly tall and even after a few weeks of consistent use I still find myself banging into the top of it when I move my hand over to grab it. This also makes it far from travel friendly, though Logitech has the Pebble for that job anyway.

The main body of the Logitech MX Master 3S is gently rubberised which gives a great, slightly soft feel against the palm of your hand and offers a little extra grip too. The left and right click buttons don’t get this treatment, but do feature a subtle matte textured finish that I have no complaints about. I’m not quite so fond of what’s underneath the Logi MX Master 3S though. There’s no storage area for the included Logi Bolt USB receiver, a feature that’s almost expected on any dongled mouse these days, and the four plastic mouse skates don’t offer the same level of performance I’ve seen from other mice, including Logi’s own G502 X Plus. They’re fine on a mouse mat or softer surface but feel a little scratchy and rough when used directly on my Autonomous Desk Eureka’s surface.

That slight friction on hard surfaces aside, the Logitech MX Master 3S is a lovely mouse to use for day to day productivity work. The snappy 8,000dpi sensitivity is more than enough to have my mouse flying around from edge to edge and I was impressed at how well it worked across different surfaces. Logi even says the MX Master 3S will work on glass as long as it’s thicker than 4mm which is rather good going.
Something that stood out for me in testing was just how quiet the Logi MX Master 3S is, no matter which button I pressed or wheel I spun the MX Master 3S remained respectfully muted. Logi appropriately calls this Quiet Clicks and claims the left and right click buttons offer 90% less noise than the MX Master 3. Each click has a pleasantly tactile feel to it and the noise they do make is oddly comforting, it’s a nice click and not a jarring one.

The Logitech MX Master 3S’ MagSpeed scroll wheel takes a little getting used to but I now miss it when I’m using other mice. The machined steel wheel offers electromagnetic scrolling and automatically switches between a rapid, 1,000 line-per-second free spinning mode and a more traditional stepped mode. It’s seriously nifty and a gamechanger for anyone consistently working in large spreadsheets, documents or webpages. There’s also a second scroll wheel sitting just above your thumb and while this will be personal preference, I found this one far less useful. Again, I’m sure there’s an element of simply needing to become accustomed to the option, it’s nicely textured and accessibly placed, but for me it’s a little too sensitive and would benefit from some added wheel resistance.
That automatic scroll wheel isn’t the Logitech MX Master 3S’ only hidden trick. Given away only by a subtle raised bump, a secret button built into the thumb rest opens up a world of gesture possibilities – if you can train yourself to use them. Honestly? I couldn’t and outside of some dedicated testing, never managed to consistently use them and ended up forgetting the button was there. Which is actually a tick in the box for a hidden button I suppose.
That doesn’t mean to say the idea isn’t great or well implemented though, because the thumb button is both of those things. The Logi Options+ app (which is also where you’ll set all of your customisation options) allows you to choose between a frankly incredible range of shortcuts and actions for the thumb button. Covering everything from simple window switching right through to opening an inbuilt AI prompter or triggering your own custom actions, it has the potential to deliver buckets of value for the right user and is well worth sinking some time into playing around with.
Across the board the Logi MX Master 3S feels like a thoughtful, well considered mouse. You get the impression a number of bright minds locked themselves in a meeting room for a week because it’s packed with loads of little quality of life touches and seems to have every box ticked. Easy-Switch lets the MX Master 3S pair and quickly switch between three different devices thanks to a button underneath and will even work seamlessly across devices with Logi Flow. Logitech claims up to 70 days battery life for the MX Master 3S and I won’t argue with that, I can’t remember the last time I plugged in the USB-C cable and the Master 3S is still reporting 61% remaining. You’ll also get three hours of use from a single minute of charging, which is mind-boggling stuff.
summed up
The Logitech MX Master 3S is simply fantastic. Going about its business with a refined classiness, this professional mouse is jam packed with features and quality of life touches that make it a joy to use for work and general productivity. It may lack the visual flair of other options, but even most gamers will struggle to find a better all-round mouse option. Sometimes it pays to notice the quiet one in the corner of the room, you never know what they’re cooking up.
Yes, £119.99 may feel like a chunky investment for a mouse but with seamless multi-device switching, massive customisation potential and a super comfortable form factor the Logitech MX Master 3S is worth paying for.
