Want to know everything about it and if it's worth the investment? LogitechCheck out our full review now!

Design and construction

O MXMaster4 It's a wireless mouse from Logitech designed for productivity and features a striking design with a distinctive silhouette. In this generation, the Logitech The company opted to focus more on sustainability, meaning it uses at least 48% post-consumer recycled plastic, low-carbon aluminum, and the battery contains 100% recycled cobalt.

This decision ensures that it is not only beautiful and has a premium feel, but also more durable and safer for users. This change directly addresses one of the main complaints about previous models. They were made of rubber and, despite being beautiful, would peel and wear out over time, something that should no longer happen with the new material.

Despite the change, it remains as good to use as the others. The ergonomics of the family MX It remains the same here. One detail is that the model continues to be designed exclusively for right-handed users, and in those cases, it fits perfectly. I don't have very large hands and I loved the grip. On the left side of the mouse, there's a small wing where you can rest your thumb, in addition to maintaining a slight incline on the sides. This shape ensures lightness and comfort for hours and hours of use without becoming uncomfortable.

It has 8 buttons, some of which are programmable via the app. Logi Options + And I'll go into more detail about them later. Finally, it's also worth mentioning that this model is repair-friendly. The mouse base has been redesigned and now features accessible screws, allowing you to open it to replace the battery if necessary after years of use.

Hardware and Performance

O MXMaster4As I mentioned before, it's excellent for productivity. It comes with... Bluetooth 5.1 Low Energy and it has its own receiver called Logi boltIn addition to being able to connect to up to 3 devices, this new receiver is now... USB-C, retiring the USB-A from previous versions.

It features a high-precision sensor. darkfield And it can reach an incredible 8000 DPI. Although it's not a gaming mouse, this number is quite important for achieving precision and speed in setups with more than one monitor and with higher resolutions and frame rates. The sensor is quite impressive and even works in unconventional locations like your mirror.

Another cool thing here is how quiet this mouse is. Previous models were already like this and the MX Master 4 It maintains tradition, being an excellent option for those who have nighttime routines and don't want to disturb others' sleep, or for the sound of the click to leak into a video or audio recording, for example.

Another thing that remains here is the rolling wheel. MagSpeedThis is the first time I've used it, and wow, it's very precise and fun to use. For me, it was like using a touchpad gesture, but on a scroll wheel, being able to go slow or fast, depending on the user's gesture. And because it's inductively powered, it seems to be a very durable piece of equipment.

Software and functionalities

As I mentioned earlier, the MXMaster4 uses the software Logi Options + to configure all its functions. It is available for Windows e MacBefore we delve into that, it's important to quickly hover your mouse over each of its buttons so I can highlight their functions and possibilities.

In addition to conventional mouse buttons, such as the right and left clicks and the middle button with vertical scrolling, this high-performance wireless mouse also features the following buttons:

• Gesture buttonThis button allows you to switch between workspaces and open the menu. Start...among other functions, depending on what you prefer to configure in the app. The mouse provides a haptic effect when we use this button.
• Spotlight effect buttonThis button provides several special effects when pressed and held, such as placing a laser on the screen, creating a magnifying glass effect, or highlighting the mouse pointer area. Extremely useful for online presentations. Google Meet, Teams and others.
• Forward and backwardAs the name suggests, they are used to move back and forth between pages without having to click on the screen icons.
• Horizontal scrollingIt functions like a touchpad, allowing you to scroll the screen left and right as well.
• Show Action Ring: activates the Action Ring menu, which brings various functions directly to the screen.

That being said, it's worth taking a look at some specific mouse features.

Action Ring

The big news here is the Action RingIt's located on the thumb button and features haptic feedback. When pressed, a wheel appears on the screen with up to 8 options. In conventional use, the options include Pause/play, emoji, print key, lock desktop, AI access, quick notes e Quick access to Logi Options+All these options can be modified in the app to the user's liking. One really cool thing is that some apps like DaVinci Resolve, Adobe Photoshop e OBS Studio They feature exclusive compatible gestures. So, when using one of these apps, upon opening the Action RingYou will have quick access to tools.

Gestures

Another interesting button is the one for GesturesBy pressing it, you open the Task display (same as pressing) Windows key + TabThe trick here is that if you press and hold the button and drag the mouse in other directions, new functions are executed. Moving upwards opens the... Start menudown you Show/Hide the workspace...in addition to being able to quickly switch between workspaces by swiping left or right. And of course, if you don't want to use that button in that way, you can change it to anything else, including... Action Ring.

Spotlight Effects

The middle mouse button is where we use the Spotlight EffectsThey are excellent for presentations, whether online or in person, and at the time of writing this review, there are three possibilities: Featured, where the mouse pointer is illuminated and everything else is dark; Enlarge, which gives a magnifying glass effect to the mouse pointer area; Laser, which works like a laser to highlight what's on the screen. Zoom and Laser allow you to change the colors according to your preference, and all of them let you change the size of the effect.

Haptic motor

Having a haptic motor in Mx Master 4 It's a detail that seems insignificant, but that's until you use the mouse. With it, you can feel certain actions performed with the mouse, adding a little extra immersion to the experience. If you've ever played anything on a... dualsense No. PS5You know what I'm talking about. It works by using the Gestureswhen activating the Action Ring and in specific apps like the PhotoshopIt's worth mentioning that if you don't like this type of feature, you can disable it.

Smart Actions

For those who enjoy automating things intelligently, that's where... Smart ActionsThis function activates several macros so you can automate your productivity. So, for example, you can choose the work mode No. Logi Options +You choose a shortcut to activate this macro, and when it's activated, the Google Chrome it will open in gmailjust like the apps Microsoft Word, Excel e Power point.

All of this can be customized, and you can also create your own macros, mainly in terms of how to activate each one, being able to switch from "Work mode" to "Leisure mode" with just one click or key combination.

Logitech flow

Finally, it is possible to use the MXMaster4 on multiple devices simultaneously. Through the app and using the same network. Wi-FiYou can use the same mouse and switch between systems. Windows to a Mac With the simple gesture of moving the mouse to the corner of the screen. It's one of the coolest features of the mouse and it's not merely a matter of usability; after all, you can literally drag an item to another PC using this action. Obviously, the larger the file, the longer the task takes, but it's still quite interesting and productive.

Battery

O MXMaster4 It's a wireless mouse from Logitech, and that alone is great for keeping your desk more organized. However, its battery life is surprisingly good. Previous models already had excellent energy performance, and this one is no different. In terms of numbers, the Logitech They put a 500mAh Li-Po battery in this little gem and promise up to 70 days of use without needing to recharge it.

It's worth mentioning that, because this version has a haptic motor, there's a concern about the battery running out quickly. Depending on how you configure this effect in the app, it will indeed consume more energy. However, even so, the mouse performs incredibly well. When I received the mouse for testing, it had about 20-30% battery remaining. I used it for a few days and then needed to charge it. Since then, over a period of almost 30 days, it remains at 85%, even with daily use for hours.

Even if you run out of battery, the charging time deserves praise. Fortunately, there's a USB-C connection on the front of the mouse, and you can continue using it while it charges. No connections on the bottom, like on Apple's mouse, for example. Charging time is around 2 to 3 hours, depending on how much battery power needs charging.

Price and availability

The high-performance wireless mouse from Logitech It arrived at the end of October 2025 for the suggested price of R$799,00You can buy it from the official store. Logitech Store or else by Amazon, also at that same value.

Conclusion

O Logitech MX Master 4 It's an excellent mouse that delivers on its promises and made me understand its reputation as the best wireless mouse for productivity. Its previous versions were already highly praised, and this new version corrects the previous problems and maintains what was good, in addition to bringing good new features, such as... Actions Ring and haptic feedback.

Replacing the old rubberized material with high-quality recycled materials is one of the biggest successes in the mouse's design and will ensure it lasts even longer than previous models. The software Logi Options + It also deserves praise for allowing us not only to use the mouse in different ways, but also for giving us the possibility to customize all the functions the way we prefer, which is great for the consumer.

Finally, it's fair to say that it's a bit pricey, but in this case, it's justified. If you're already a productive person, it will make your work even more productive, and that's where my recommendation comes in. Buying this mouse thinking it will change your routine on its own is an exaggeration. It greatly facilitates the lives of those who already have productive habits on their PC. For those who have these habits and use... Windows ou MacI consider this mouse indispensable and an excellent investment.

Now, if your goal is gaming, or if you only use your PC for very basic tasks, then what would be an investment becomes money thrown away, and it might be worthwhile to opt for models designed for those uses. In any case, it's safe to say that... MXMaster4 It's a great evolution of the line and delivers exemplary results for those seeking productivity.
