Absolutely Rare

[This review was collected as part of a promotion.] Wanted to use my iMac with my touchscreen HP desktop. This is the only product on planet Earth which can make this possible.

Excellent mouse.

Tactile, comfortable, accurate...a joy to use. Recommended if you have bigger hands as well.

Ergonomically perfect, practically brilliant!

I bought two of the mice (mouses?) for both my PC and Mac. I use them for CAD and they’re simply perfect. They’re ergonomically outstanding and I can use them comfortably for hours. One of the best mouses (😉) I’ve ever purchased.

Very happy as a full time college student!

So its been about a month since I purchased the mx master 4, and as a whole I am extremely happy with my purchase. As a college student whos life now predominantly revolves around work on my laptop having a good, comfortable, portable, and overall practical mouse became more and more crucial to my everyday work life. Being a college student with only a part time job however also meant that making a purchase of this price took alot of thinking over. It's no secret the mx master 4 isnt a cheap mouse and that there arent countless other options available on the market that would suit your simple day to. If you only need a computer mouse for odd bits and bobs here and there for short periods of time then maybe this mouse isnt for you. However, if you want to have the best, most feature packed, and just down right comfortable work experience then the mx master 4 is the way to go. The mx master 4 is especially useful when working in quiet environments (the college library for one) where you dont want to disturb others but also dont want to have to rely on an uncomfortable trackpad for hours on end. Saying all of this, no product is perfect and there are some caveats that I would like to address. 1) I have found myself using the quick switch features quite often to quickly go from my desktop, laptop, and phone seamlessly (an amazing feature!) However, having this button located on the underside of the mouse makes it an absolute pain if I wish to swap between devices quickly. (You can set up the custom mx master 4 shortcut wheel in the logioptions+ app to switch to certain quickswitch devices however this is limited to computers and does not work on mobile devices). Seeing an updated version where tgis quickshift button is located somewhere more accessible would be amazing. 2) I have found that the logiwheel that you can configure with the logioptions+ software has had some bugs, for example certain shortcuts and macros not working. This is just a generalised issue which I would like to see resolved in future updates. Overall, I am very happy with my purchase and believe that people who have a similar use case scenario as me will find it extremely worth while in the long run.

Feature-Packed and Great for Productivity, but Slightly Heavy

I’m very happy with the MX Master 4 overall. It has some really useful features, especially the scrolling wheel and the button that lets you toggle the scrolling mode on and off. I also really like the side buttons and the customisation options. The side thumb button is very handy, and the horizontal scroll wheel is especially useful when working with large Excel spreadsheets, as it makes it easy to scroll left and right without having to use the scroll bar. My only concern is the weight. The mouse feels a little heavy when moving it around, and because of that, hand movements can sometimes feel slightly less effortless than with a lighter mouse. Overall, though, it’s a very comfortable and feature-packed mouse, particularly for office work, Excel and productivity.

A great tool.

The mouse is very comfortable to use and is of great quality - it feels like I have been using it forever. I must confess that I had a little difficulty customising it for use with Lightroom Classic and I found the set up instructions could have been better. However, once I got the hang of programming it I did it very quickly and it was certainly worth the effort. This is a great tool especially when paired with the matching keyboard.

Action-ring: overrated or still in 'beta'?

[This review was collected as part of a promotion.] I bought this a month ago, because I previously had an MX master 3 at work and since I liked that one I thought let's get the upgrade.. Might be good to mention that workplace was windows and my personal is MacOS primarily, but I wanted the USB-C receiver version, cos let's face it it costs the same and previously I had problems with my BT (on win10) so wanted to have the option to connect without BT). All the regular buttons and the mouse works perfectly on a regular basis, but from time to time in this past month I am having problems with accessing the action ring features. Most of the time when I press it and the options of actions should pop-up nothing happens.. so I have to launch the options+ app and find out what is happening. Sometimes it starts to work right after launching it, sometimes I have to update it (which means quitting all adobe and then updating), and one time I had to ask for logi-support (they were great though, thanks!) But because of these sometimes I think it is just a bit too much trouble for button options I'm still not very comfortable with.. The MX-3 had one single button there and I set it to access screenshot/capture function and that was very neat and efficient (although I remember I had to launch the logi-options reguraly (almost daily), because the mouse forgot I prefer the inverted scrolling.. but after launching it always remembered). Anyway I am not yet positive I chose the right model, I guess I need to use it for longer to find out and see if the future updates will bring some positive change in the accessibility of the action ring.

AI Is Not The Answer

The update to the MX 3 has an improved design, but falls foul of ingrained habits. In trying to improve on perfection with the addition of AI, Logi have overstepped usefulness. The Actions Ring button and haptics replace the Gesture button on the MX 3, albeit at a slightly different place which makes changing between the two mice maddening. It takes some getting used to the thumb-tip position of the Actions Ring button. The movement to use either is different: a grip action on the MX 4 compared to an extending motion and downward press of the thumb on the MX 3. The Gestures button on the 4 has been moved in front of the Forwards and Back buttons, and is slightly too far out of reach to be as useful as it was on the flat thumb rest of the 3. Gestures, built into the MX 3, in its default position, has become second nature to me. Not having a Gestures button where I expect it is like having a thumb injury: I can still use the mouse, but the click I am used to doesn’t work and I experience a momentary panic. My mouse is broken. The Actions Button has haptic feedback. Unlike the Gestures button on the MX 3, which has one very particular point that can be pressed, the Actions button can be pressed at any point on its surface. By default, it opens the Actions Ring, which is where it has fallen foul of my deeply ingrained habits and where Logitech have sprinkled some AI sauce in their hope of improving on perfection. The Ring can be set to include eight shortcuts, which can contain shortcuts within them that break off like goo in a neat/needless animation (delete as appropriate to your taste in whimsy; I rather like it), one of which is Explore AI. In this submenu are four different options for four different AIs: Reply with ChatGPT, Ask Perplexity, Rephrase with Gemini, Open MS Copilot. These can be further orchestrated to carry out specific requests of each AI. Logitech have decided that this implementation of AI is the answer to further improve and differentiate the MX 4 from its older sibling. AI is not the answer. AI is never the answer. AI can help find, phrase, decide on, or otherwise discover the answer, as can any appropriate tool, but it is not the answer. As with cheap keyboards that market themselves as better with the a series of rubbish plastic buttons, one of which is marked with a globe to signifying opening a browser and another with @ symbol to open email client, a shortcut button to choose your preferred AI client is not the way to improve on a product. Even appreciating that this is a demonstration of what can be done with the button, it is a crippling amount of choice and setup that only the most ardent AI fan would want to make use of. Other options are play/pause music, which is easier done with the shortcut key on F9 on my Logitech keyboard, typically in reach of either my first or middle fingers of my right hand. Any shortcut that tries to replace something done with these fingers is utterly pointless: nothing will be faster than what I can poke at with an index finger, particularly not something which requires squeezing something with my entire hand and making a deliberate motion with my wrist (joke here), as is required to make use of the Action Ring. This is particularly egregious when that squeeze-and-move motion was used to move between virtual desktops. Any user with even the slightest amount of history with the MX 3 is going to be driven up a wall by this change and further aggrieved that Gesture has been mapped to a new third button in front of the Back/Forward buttons. This button is out of reach and its positioning makes it more difficult to flit between desktops, as has become my habit. These buttons can be remapped in Logi Options+, but this introduces another issue with the haptic engine: move between desktops and the haptic will click back against your thumb, sending a pulse that can be felt through the length of the thumb, the instinctive response to which is stop holding the mouse. More specifically, the response is “Argh! What the hell is that?! Drop it! Drop it!”, which is not an experience you want when using a mouse. Like the other programmable buttons on both MXes, the Action Ring can have application specific shortcuts. Here I thought might be its saving grace. This was most relevant to me in Lightroom, where eight of properties of an image were mapped to the Ring: Exposure, colour temp, Vibrancy, etc. Selecting the property from the Ring would then allow the horizontal scroll wheel to changes the values rather than direct indirection with the sliders. There might be some value to this in theory, perhaps to throw a quick edit together before knocking at hairs and perfecting the image with sliders. The problem is that it simply doesn’t work. It first depends on opening the Action Ring when the properties and their sliders are *right there* on the screen, beside the image. Second, it relies on the user recognising the property from its icon in the Action Ring, which I’m sure many power users do, but this amateur does not. Hovering the cursor over the icons does bring up the name, but at this point, you might have well as moved the cursor over to the slider on the right of the screen. This means you have to squeeze the mouse/click the Actions Ring *before* clicking onto the quality to edit (assuming you recognise them by their logos), then edit by button. Which feels far more convoluted compared to moving a slider. More than either of these points, the entire endeavour is doomed from the off by its implementation. The value change is done by a coded shortcut and doesn’t interact with the property directly. This causes massive lag, a literal sit-and-wait pause between an incremental move of the scroll wheel and the change being applied to the image, rendering the entire operation pointless: a near-instant change to the image can be made by either moving the slider in Lightroom’s interface or by selecting the value and changing it with the +/- keys (actually =/-, but we won’t quibble). This might be Mac-specific, but even if it is, it certainly is not worth changing operating system for. Similar shortcuts are mapped to the Ring in Excel, an application I spend an unhealthy amount of time in. So much time, in fact, that I have shortcuts and functions mapped into my fingertips; I see use of a mouse in Excel as skill issue on my part. A non-haptic, easier-to-depress Gestures button would have been a great update, and the overall look of MX 4 is an improvement over the now seven-year-old MX 3. The new mouse has a smooth plateau, the horizontal scroll wheel becomes part of that flattop design, and the *logi* logo beneath the clear plastic of the left button is a nice touch, though how well that will age, physically, as the plastic is worn by years of clicks, and in terms of taste, remains be to seen. Its smoother, carbon fibre-like finish is preferable to the rougher, almost tacky feel of the MX 3 as well. As an item of desk furniture, the updated 4 is more attractive than its older sibling, but as a functional piece of equipment, its addition features detract from usability and for that it suffers. Within the shape and structure of the MX 4 is a better MX 3.5, and perhaps even enough for it to have warranted the increase of integer. But in overreaching, Logitech have dropped the ball and the mouse with it, making a product that is not only less than the sum of its part but decidedly less than the product they set out to replace. And for that, this is a two star product. Over-engineered, and over-priced for it, even more so the already expensive MX 3.

Very good

The MX Master 4 is hands down the best productivity mouse I’ve used. It’s incredibly comfortable, the MagSpeed scroll wheel is buttery smooth, and the customizable buttons make everyday work much faster. The battery life is excellent, and switching between multiple devices is effortless. Pricey, but absolutely worth it if you spend long hours on your computer.
