Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, Black

Great mouse. I am annoyed with the change in the button placement for mac gestures given my muscle memory from the Master 3, but it's not bad after getting used to it. I do find myself accidentally pushing the button my thumb rests on a lot. If you're used to the older variants, it will take some learning to change the muscle memory.

Overall, the mouse is excellent and works very well in daily use. However, there are a couple of minor issues worth noting. First, on Windows 11, the Action Ring takes a few seconds to activate after startup or waking from sleep, which feels slightly inconvenient. Second, the current selection of plugins for the Action Ring is quite limited. It mainly supports Adobe apps, DaVinci Resolve, and a few others. It would be great to see broader support, for example a plugin for Blender. As a workaround, I configured additional buttons for navigation in Blender, and that works well. Aside from these points, everything else performs great.

As a previous user of the MX Master 3S, I can confidently say that the MX Master 4 is on a whole different level. I am extremely satisfied with this purchase! Premium Innovation: The new haptic feedback system gives a fantastic tactile response that makes scrolling and navigating intuitive. Actions Ring: This new button feature is a game-changer, giving instant access to shortcuts directly at your cursor and saving massive amounts of time. Superior Build: The materials feel much more premium and solid in the hand compared to older generations. It is smooth, whisper-quiet, and provides the ultimate navigation experience. 100% recommended for any professional!

Just as the MX Master 3, this is an excellent mouse. With the added features, I would say that this is a close to perfect as you can get in a mouse as far as functionality. I do not game, so my usage is leisure and work. It gets the job done. The only thing I would suggest is that the overall footprint was smaller. I do get hand fatigue occasionally.

A great gaming device delivers more than just power; it creates immersion. From smooth, lag-free performance to stunning graphics and responsive controls, every detail works together to pull you deeper into the game. Whether you're battling online, exploring open worlds, or competing at a high level, a reliable system ensures you stay focused without interruptions.

The MX Master 3 was a daily driver since 2020. The 4 has a better mouse casing (no rubber, easier to clean). It also has superior software accompaniment allowing you to customize the buttons. If youre in biz and are shifting between apps / in nuanced workflows, this is worth it (early on). I typically use an iso alcohol / water mix with compressed air weekly to keep the mouse clean 🤜🏻.

The only reason I am not giving it 5 starts, is that the "height" of the mouse, as it sits in your palm, is lower than the MX 3 (which I love and used since it's release). So, sometimes you inadvertently push the thumb button as your moving the mouse. Wish they had kept the height EXACTLY the same as the MX3.

I really enjoy this mouse, the clicks are quiet and is the perfect size. I have a small hand and have no issues using the mouse. I have two things I would like to make a commentary on… 1 is I use this for my WFH set up and my company policy does not allow us to download the most recent version of Logi Options+, so I'm not able to use the mouse for its max capabilities. 2 the scroll is clean, but it is a bit sensitive so it may scroll longer than I wanted and end up zooming in and out of things. Both of these are user error related so don't take this review as negative. I would recommend buying it if you are looking for a new mouse.

Unfortunately, I'm returning it. Used MX Master 3 for years before this and LOVED IT. I was excited to get this new experience and try the new haptic button. The thing I valued the most on my Master 3 was the button below your thumb that I used to "close window" or "close tab" in a browser. I was ready to try the new haptic button. When I got the mouse I had two physical issues. First, the texture of the overall mouse body was too smooth, only the right side edge and the haptic button had any grip. It made me notice that heavily relied on the palm of my hand to do a lot of my mouse movement. The MX 3 has the rubber texture all over the mouse (or maybe mine is just old and sticky and the MX 4 would have got that way eventually). The smoothness of the MX4 did not allow me to make the same movements and I noticed the mouse slipping out of my hand. Second, I do not like the bumpy texture on the thumb button. I found that the pad of my thumb became irritated after an hour of use. As for the haptic button functionality, I found it difficult to use. The setup was fine, but it was slow to initiate and in many cases you had to have an application as your ACTIVE window for any of the actions to work. I found that it was just faster to make the click in the window or app in the usual way instead of waiting for the feature to execute the command once the button was pressed. One key example was that I wanted to have the calculator be one of the apps that was launched, but it always launched behind any of my open windows, so it was just easier to launch the calculator from my quick launch as usual. Again, I love my MX master 3 (and will be buying a new one).

The Logitech MX4 feels too heavy and doesn't offer the same comfortable grip as the MX3S. As a trader, I prefer a lighter mouse that's faster and more precise, and the MX4 doesn't match the speed and accuracy I need for long trading sessions. maybe because of the weight.
