Customer Ratings & Reviews

Considering the price increase from $99, the MX Master 4 mouse had some pretty big shoes to fill coming from the 3s series. As my favorite mouse for many years now, the simplicity, ease of use, and premium materials warranted my purchase, with this mouse being no exception. ***PROS*** + Out of the box, the Master 4 mimics the silhouette of the Master series as a whole, exemplifying the ergonomic- and productivity-focused design seen its predecessors. Making the horizontal scroll wheel larger and moving it up the ridge of the device allows for a >180 degree range of motion, thus allowing the 4 to surpass the 3s and its recessed nature. + The 4 implements an intuitive haptics system* (<-see cons) that connects the user to the interface, buzzing when pairing the device, moving between windows, and using the newly integrated actions ring, allowing the user to access apps and actions with the click of a button. + Fixes issues with clunks, vibrations, and "stickiness" associated with the 3s and its scroll wheel, an issue that drove me crazy. (Specifically when I stopped scrolling and the magnet would click back in, along with a loud clunk.) +Improved click noise, incorporated smoother scrolling, and solidified the metal vertical scroll wheel to mitigate horizontal movement/play. + Switched the main body from (notoriously fragile) soft-touch rubber to a textured high-quality plastic, helping with sweat buildup and the ability to keep the mouse clean. Surprisingly comfortable considering how much I loved the material for the 3s. + Moved the tab-switching button from the thumb joint (sometimes awkward for smaller hands) to the actual thumb, along with an EXTRA programmable button for preferential customization. + USB-C dongle for Logi is always a plus. Going in the right direction with their compatibility. +Screw holes allow serviceability & right to repair ***CONS*** (-1.25⭐) - (*<-From before) Logi Options+ MUST be installed to use the haptics on the mouse in a meaningful way. There is NO on-board memory. Users working in a company that blocks 3rd party software LOOK ELSEWHERE, or, get the 3s. Thank goodness the software is free. (-.5) - Standard 125 Hz polling rate. This is an outdated and honestly confusing omission from this mouse, regardless of its "work and productivity" niche. This makes using the mouse on 120Hz+ monitors a drag, with the mouse "catching up" to the display. Considering you can purchase a productivity-based mouse with a 8000Hz polling rate for $70, this is a terrible look for Logitech. They are lucky the majority of monitors and computers are only 60Hz, including mine. (-.5) - On the 3s, there was a small solid plastic lip that allowed my ring finger to rest but not interfere with the mouse. Due to the refreshed design, I need to rest that finger on the right-click button, alongside my middle finger. This leads to misclicks but will be something to get used to. (-.25) CONCLUSION: Overall, this is a thoughtfully designed, well built, and multifaceted mouse. I will be keeping it, however, my 3s is on standby due to the software limitations of the 4's full functionality. 4 ⭐ because the haptics are cool (+.25), and 3.75 doesn't exist for Best Buy reviews.

Using the Logitech MX Master 4 every day has genuinely changed how I work at my desk; it feels like the kind of mouse you stop noticing because everything just flows a bit smoother. The shape is really comfortable for long sessions, with a solid, slightly heavy feel that keeps my hand relaxed instead of clawed, and the thumb rest plus extra buttons are actually usable rather than just being there for show. The main scroll wheel is incredibly smooth and being able to flick it into free‑spin to fly down long PDFs or spreadsheets, then go back to precise steps, makes big documents way less tedious, while the side thumb wheel is perfect for horizontal scrolling in timelines and wide sheets. What surprised me most is how much I rely on the customizable buttons and gestures now: I’ve got them mapped to switching desktops, media controls, copy/paste, and a few app‑specific shortcuts, so I reach for the keyboard a lot less. Battery life hasn’t been a worry at all—weeks go by without charging, and even when I forget and it runs low, a quick plug‑in over USB‑C during a break is enough to keep me going. It’s definitely not a competitive gaming mouse (it feels too heavy and not as snappy as esports gear), and the price stings a bit, but as a daily workhorse for productivity and creative work, it feels absolutely worth it and hard to give up once you’re used to it.

In terms of ergonomics for people with carpal tunnel, this is an excellent mouse. An upgrade from the MX Master 3S in the sense that it gets rid of the awful rubber that was all over that mouse. The shape also seems refined. Good tracking. Excellent battery life. The only downside is like with other Logitech Master products is that there is no onboard memory. Therefore, if you can't install and login into Logi+ on a business PC, then you can't customize the mouse, or use the side scroll wheel at all. I still rate it four stars for comfortable use for 8 hours a day at work.

This mouse is the nicest one I’ve ever owned, which it should be for 125$. My favorite part is that it is fully customizable and I can change the commands of all of the different buttons to whatever I want. So instead of having to ctrl c-v I can just copy-paste with the touch of a button. The mouse clicker also makes minimal noise and is flirty comfortable to use for 8 hours a day.

I’ve been using the Logitech MX Master 4 (Adobe Edition) for my photography and editing workflow, and it’s honestly one of the best upgrades I’ve made. The precision is on point, especially when working in Lightroom and Photoshop everything feels smooth and controlled. The customizable buttons make a huge difference. Being able to map shortcuts for editing speeds up my workflow a lot, and the horizontal scroll wheel is clutch for timelines and detailed adjustments. The ergonomic design is also perfect for long editing sessions no hand fatigue at all. Battery life is solid, and the wireless connection is reliable with no lag. Overall, if you’re a creative, photographer, or editor, this mouse is definitely worth it.

The mouse has a great feel. I saw more positivity online about the 3S but decided to go with the new model anyways. The matte finish is supposed to be for more stain resistance but after not using it very long it seems like friction is wearing the finish down already on the left click. Either way, I like the gesture button - don't use it very much but it seems cool if it can become second nature. The feel in the hand was just great. I thought it was ok when testing it in store but once I brought it home and started using it, it started to feel much more natural much more quickly.

I’m a financial analyst and I primarily work in excel, this use of this mouse can’t be understated. I am able to efficiently scroll through worksheets both up and down and side to side. This is paramount for large scale financial models and spreadsheets. Not to mention the programmable buttons through the LogiOptionsPlus application. You will likely need clearance from your IT department download to your work machine but it I couldn’t recommend this enough for individuals in accounting and finance. The comfort is something to be experienced!

I'm using this mouse on a MacBook Pro. Im really loving it so far. It solves all the macbook mouse issues i was having, such as not being able to turn off mouse acceleration, not being able to invert the scrollwheel direction without also inverting it on the trackpad, etc.... The only thing I'm a little iffy on is the thumb rest button. I click it by accident a lot,but I'm getting used to it. The ridiculous battery in this mouse makes up for that.

The mouse is excellent in most ways. I cannot figure out why it scrolls the opposite direction randomly in Windows 11. Besides this annoyance, it is nearly perfect. The battery lasts a long time. The number of buttons and software options give me per program programming options which makes it great for a power user like me.

Excellent mouse. Does everything I could want and more.

Amazing product! Not sure how I did without for so long. Game changer

This mouse is just what I need. Helps with wrist stability and mitigating pain tremendously.

I picked up the Logitech MX Master 4 at Best Buy, and I couldn’t be happier with both the product and the shopping experience. The mouse is incredibly smooth with my Mac, comfortable, and packed with smart features that boost my productivity. Best Buy had it in stock, the price was great, and the staff was knowledgeable and helpful. Overall, a perfect purchase — highly recommended!

Plain and simple: if you are looking for a wireless, ergonomic, right-handed mouse with all the productivity shortcuts you could think of, this is what you need. I’ve never used a mouse that feels this premium and worthy of such a adjective. I will preface this review by saying I’ve almost exclusively used Logitech mouse for over a decade. Particularly their mice that are ergonomically shaped and have two side thumb buttons. I’ve been using their Marathon Mouse M705 for years and I’m quite happy with it. When I had the opportunity to check out the MX Master 4, I was super excited because it had some interesting features I wished to check out! There are several features that drew me to the MX Master 4 as someone who works remotely at a desktop every day. Firstly, is the ergonomic shape. If I don’t find the mouse comfortable for my hand to rest on and slide around, no other feature will overcome this. I can say that as a right-handed mouse user, this fits and feels well. I was concerned slightly about the extended thumb area – both with it sticking out farther than I’m used to, the textured area, and that it’s also a clickable button. I can say that none of this bothers me and the placement of the action center button and the three thumb buttons above it are perfectly out of the way. It does seem slightly heavier than my previous mouse, so I adjusted some cursor settings so that I don’t have to physically move the mouse as far as I prefer not to have to lift the mouse. It’s also worth noting that this is a very large mouse – larger than the Marathon Mouse. I’ve included a photograph comparing the two. If you have small hands, I think this may be too much. All of the other features are a plus. It is a rechargeable, something I’ve not had in a mouse before. Logitech claims 1 minute of charge time gets you 3 hours of use and a full charge is about 70 days. This works just fine for me and saves me the hassle of requiring batteries on hand – else you lose all control of your mouse! It charges via USB-C, so at no point will you need this plugged in for hours on end. The horizontal scroll wheel is a treat. As someone who works frequently in spreadsheets, this has already come in handy. The wheel is the perfect amount of slow tension. At no point will this wheel scroll more or less than precisely where you need it to be. This can be customized using the Logitech software to work differently depending on the current application. For example, on web browsers you can set it to scroll your open tabs. The main vertical mouse wheel, located between the left and right click buttons is also an improvement over any other mouse I’ve used. It features two modes: a tactile scroll and a freewheel smooth scroll. I like tactile, but in the past, it has been too noisy for my preferences. This time around, it’s silent and the tactile feel is haptic. There is a small button below the wheel that switches between both modes. Of note is that this time around it’s smart: by default, it’s the tactile scroll until you scroll fast at which point it switches automatically to smooth until you’ve paused. This sounds confusing, but in practice it is completely natural and welcome! Speaking of silent features, something I had overlooked was that the left and right mouse button clicks are completely silent! To be honest, this has thrown me for a loop more than anything else. I did not realize how my brain has come to rely on a mouse click, well, making a click sound. After a few days though, I’m more comfortable with the silence. There are four more buttons yet to be talked about: There are two thumb buttons that by default and by my personal preference are for forward and back. Most of my work is in web browsers and going back and forward is very common and these thumb buttons save time. There is a third thumb button slightly more forward from the proximity of the other two that’s a gesture button. You can program a single click to do, well, whatever you’d like, and you can then hold the button while moving your mouse in an orthogonal direction to act as four different other actions. All three thumb buttons and gestures, with the Logitech software, are customizable. The last button is Logitech’s touted Action Ring button. This is a button that will activate a ring of selections around your cursor on the screen. What these selections are can be customized individually and can also be app dependent. In other words, it can be different options in Microsoft Word as it is in Zoom or Photoshop. This is a whole secondary world of shortcuts, all programable via the Logitech Options + software. You can download app specific options, which include a lot of productivity software, on top of every Windows shortcut you can think of. Or create your own macro. To be honest, while impressive and intuitive, I’m not sure I’ll be taking advantage of this too often. Most of the app defaulted action ring shortcuts are the buttons in an application you’d most often select and therefore are front and center in your application. I’m not sure I’d ever get the muscle memory to click the action ring button and click the action versus just moving my mouse to the appropriate place to click within the app. However, for a button that’s unobtrusive, having the option there is amazing. I can see someone else taking far more advantage of this than me. As for the unboxing and setting up of the MX Master 4, it simply couldn’t be easier. In the box is the mouse, pre-charged just around 55%, the USB-C receiver and some brief documentation. On the underside of the mouse is a large, easily removable sticker, that instructs you on what to do if you’re looking to connect via Bluetooth or via the USB-C receiver. Of note is that the USB-C receiver has no USB-C to A adapters – your computer must have an available USB-C port. My Windows 11 computer immediately recognized the mouse upon plugging in the receiver and turning the mouse on. From there, it was a quick download of the Logitech Options + software. As mentioned, the software can help customize everything this mouse does. No button is off limits from customization, and the software does a good job of introducing you to all the features and how to change them. The software allows a deep level of customization. You can adjust what your mouse buttons do on a per application basis, something I’ve only briefly played with. To be honest, this level of customization at times felt overwhelming. I plan on revisiting the customization options down the road, as it was too much during my initial set up to think about all the potential possibilities this can provide. Bottom line is if you are a remote worker who loves buttons and loves productivity, I can’t see how you’d go wrong with this mouse. I’m not sure if it’s an apt comparison these days, but this is the Cadillac of computer mice. Any mouse will let you move your cursor and click, but this one makes you not only enjoy the experience, but tailor it specifically towards your needs and in the process saves you time.

I've used each model as they have upgraded and this one really does feel like an upgrade. Secifically love the scroll customization.

Great mouse to use and super silent. Great for work

I’ve always tended to think of the MX Master mice as the de facto choice for ‘best’ mouse when it comes to productivity and creative work and the MX Master 4 doesn’t do anything to change my opinion about that. The ergonomics are still my favorite out of all the mice I’ve used, the materials are better, and the performance is great. The new haptic button is a nice addition, but its utility so far for me is limited. It’s definitely an iterative upgrade over the previous MX Master 3 and 3S, but the changes that are there are welcome. In the box you get the mouse, a USB-C Logi Bolt dongle, some documentation, and that’s it. I was surprised to see that a charging cord was not included. It’s not the biggest deal as the mouse charges over USB-C and I’ve got tons of those cables, but it really feels like something so basic should have been included for a high-end product like this. The mouse carries over the same shape as the MX Master 3 and it fits my larger hand great. It still has the same aluminum scroll wheels. The finish on the MX Master 4 did get a change and it’s supposed to be more resistant to wear - it’s hard to really say how much of an effect this will have after less than a week, but I haven’t seen any signs of wearing or felt the need to clean it. My 3S has developed some faint marks where my fingers rest on it, so I’m hoping MX Master 4 doesn’t suffer the same fate. The MX Master 4 can connect either via Bluetooth or the Logi Bolt dongle and you can pair and switch it between 3 different devices. The USB-C Logi Bolt dongle is new for the MX Master 4 and it’s very compact - on a laptop it hardly sticks out at all. In terms of performance the Logi Bolt is supposed to be able to minimize interference and latency in environments where there are lots of different devices compared to a standard Bluetooth connection. Once connected to my Windows PC, I setup and configured it through the the Logi Options+ application. Logi Options+ enables things like the Action Ring and offers a decent amount of configuration for the Master 4. The sensor on the MX Master 4 defaults at 1000 DPI, but can be pushed all the way to 8000 DPI. A gaming mouse the MX Master 4 is not and the 125 Hz polling rate does not impress in that regard. I’ve been through just about a full work week using the MX Master 4 and it feels pretty much like using the 3S before. The connection via Logi Bolt is solid and I’ve seen no drops on the connection. The left and right click buttons carry over the Quiet Clicks that were introduced in the MX Master 3S as the name suggests they are very quiet. The haptic button occupies the entire thumb rest - I’ve seen some people online complain of accidentally triggering it, but it hasn’t been an issue for me. It is easy to press, but does require some intention. Pressing it by default brings up the Action Ring, which is a set of customizable commands. Mousing over the different actions elicits a haptic response, which feels pretty good, though that haptic response in my experience is only limited to certain Logitech-specific commands like using the Gesture control to swap desktops. Even with that, there’s feedback on the other gestures like minimizing all windows or pulling up the start menu. The haptic intensity is set at medium by default, but it can be adjusted one level higher or 2 levels lower. I like the idea of the haptic button, but it feels a bit incomplete right now. Maybe as time goes on there will be more support for it. The scroll wheel remains a highlight on the new MX Master 4 and it effortlessly switches between the incremental clicks to the free-spinning long lists and back again. I wish Logitech would bring that scroll wheel to the MX Vertical too. Logitech advertises up to 70 days of battery life for the MX Master 4, which is similar to what the 3S was rated at. I never really tracked it and I haven’t had the MX Master 4 long enough to say, but in the time I’ve used the charge level has not visibly dropped. If it’s the kind of thing I have to charge every month and a half or so, that's good enough for me. Overall, I’m as happy with MX Master 4 as I was with the 3S. It makes some sensible improvements and while I’m still not fully convinced of the haptic feedback, I’d be just as happy if it wasn’t there. $120 is definitely not nothing for a mouse and it’s $20 more than the 3S was when it came out, but if you’re using a mouse 8+ hours a day like I think this is one is worth considering.

I should have waited now that I see others are posting similar thoughts. I've had every one of these mx devices, always look forward to better precision and features. But this one is tough to feel good about. Imagine someone walks into your office for an interview, presents a hand and it just seems to disintegrate when you go to shake it. That's this mouse. I'll point out like others how slippery it is, but it's worse than that. I dare say it just feels gross, like slime compared to the 3. Worse yet is that there is LESS friction with the pad or whatever you use it on. This is better for glass / marble etc (the 3 felt like a puck on ice), but if you use a pad of any kind it's a little tougher to move the mouse around. This only compounds the slippery mouse problem. I've given it 5 days and tried small rubber grip dots on it to match inflection points in my palm. I still can't stand using it. The only reason I gave two stars is because it's nice to have a few more programmable buttons.

Very nice ergonomically, feels premium in the hand. The engineering is nice

Smooth scroll wheel, great ergonomics, excellent Logitech software customization, reliable wireless, pricey but premium feel. Great for productivity.
