A tour around the Logitech MX Master 4

With the MX Master 4, Logitech once again raises the bar for their most popular productivity mouse. The big news is haptic feedback, where small vibrations provide a noticeable physical response to shortcuts, notifications or certain actions. Of course, it can all be customized in Logi Options+, so you decide when and how strong the feedback should be. This makes the mouse much more interactive in use and feels like a step in a new direction for the MX series.

Design-wise, Logitech sticks to what has made the MX Master a favorite among many for design and office tasks. The shape is still clearly ergonomic, with a high profile and a distinct thumb rest that provides a natural angle for the wrist. Comparing the MX Master 4 to the MX Master 3 or 3S, the differences are small but present.

The click buttons on top have been widened and extended further out towards the sides, making them feel easier to hit. The surface material has also been given a makeover, with Logitech moving away from the softer rubber coating that could wear and get sticky over time, to a textured plastic that both provides a better grip and should be more durable in the long run. It may feel a little harder under your fingers, but it also makes for a mouse that better withstands greasy fingers and frequent use.

The thumb area has been slightly redesigned. The grip is divided into several sections with different textures, and the gesture button has been moved closer to the side wheel and other buttons.

This means it's easier to activate gestures without having to move your hand as much, and together with the improved thumb wheel, overall navigation becomes more fluid.

The thumb wheel has also become easier to move, making horizontal scrolling and precision work a bit more comfortable than before.

One of the big stars of the MX Master mice is the MagSpeed scroll wheel on top, and that's still the case with the MX Master 4. It can still fire through 1,000 lines per second, but will also stop at a single pixel if you need it.

Together with an 8,000 DPI sensor that works on virtually any surface, even glass, it makes the MX Master 4 a mouse that can adapt to both huge screen setups and detailed graphic work.

The click feel has changed significantly in this version. Logitech has introduced their Quiet Clicks, which reduce noise by up to 90% compared to the MX Master 3.

This means that the buttons still have a distinct click, but without the loud, sharp sound that could be distracting in a quiet office or during meetings. It provides a more subdued experience and was actually one of the adjustments that I noticed a lot during my testing.

The entire package weighs around 150 grams, making it noticeably heavier than many other mice we look at for the gaming segment. This is a deliberate choice on Logitech's part, as the weight helps give the mouse a stable and precise feel.

For users with large hands, the shape may feel perfectly balanced, while people with smaller hands may find it a bit large and takes some getting used to.

The materials and build quality have also been upgraded. Logitech has added low-carbon aluminum to the thumb wheel, used up to 54% recycled plastic (depending on color), and the battery is made with 100% recycled cobalt.

The surface has a combination of hard plastic on top and micro-textures on the sides, which gives both a modern look and better durability.

Battery life is still impressive and Logitech promises up to 70 days on a full charge, and with USB-C quick charge you can get three hours of use in just one minute of charging.

MX Master 4 can be paired with up to three devices via Easy-Switch and used across systems with Logitech's Flow feature, where the mouse and keyboard can be easily moved between multiple computers.

Software

Controlling and customizing the Logitech MX Master 4 is done via Logitech's Options+ software.

In the software you have the option to check the status of the battery in the MX Master 4, but of course also customize the many different shortcuts that are available via both the motion shortcuts and Logitech's Actions Ring. There is a good option to customize the functions of seven buttons on the mouse, and you can change things to a wide range of functions and shortcuts.

This gives you great opportunities to adapt the many options with MX Master 4 to your own workflow. This is, for example, very relevant in programs like Photoshop or similar. which can be used in many different ways. Here it makes great sense to set up the Actions Ring shortcuts for the functions that you use most often.

Logitech Options+ is now well-proven and provides great opportunities to customize your Logitech devices so that they work optimally with your needs and workflow.

Test

I've been using the Logitech MX Master 4 for a few weeks for my work. It's a pretty even split between writing and graphic work.

Compared to the gaming mice I usually use, the size and weight of the MX Master 4 is of course a bit of a leap. After all, it is more than triple the weight of the last few mice I have tested.

It feels nice and comfortable in the hand, and for a medium-sized hand like mine, a palm grip ends up feeling incredibly comfortable.

However, I found that the MX Master 4 gave me a little too much resistance on the faux leather surface I have on one of my desks. Whether it's the surface, the feet that the MX Master 4 comes with, the weight, or a combination of the three, I can't say. Switching to a normal cloth mouse pad solved the problem, even though it did visually ruin the style of the desk a bit.

However, I have never had any issues with the mouse tracking, no matter what surface I tested it on. It has been a variety of different mats and desks, and on all of them the MX Master 4 did the job beautifully.

If a mouse like the MX Master 4 is to be worth the money, it largely depends on whether you incorporate the special options like Gesture Controls, and now also the Action Ring, which you get with the MX Master 4.

Together, these two things provide an incredible number of opportunities to quickly and effectively improve your workflow. It has been great to see useful options for both general desktop use and more program-specific solutions like Photoshop.

The shortcuts and possibilities haven't fully sunk into my spine yet, but despite that, I can appreciate the good opportunities.

The big question mark here is the future support for the new Action Ring shortcuts. Currently, in addition to regular shortcuts, there are only program-specific options with Plugins for Adobe Illustrator, Lightroom Classic, Photoshop, Premiere Pro and Zoom, which in the big picture is not much.

Logitech has said that more is on the way, but our starting point is always to evaluate products based on current features and not based on any promised additions or updates.

So currently, the MX Master 4 makes the most sense, in relation to the new Action Ring feature, if you use any of the supported applications a lot.

The latest new feature is Haptic Feedback. A small vibration motor like we know from our smartphones. It provides noticeable feedback in certain situations to support things like menus or notifications.

This is for example when you use and navigate in the Action Ring menus or when you receive notifications in Windows. It's a nice little addition that gives a nice little boost to the mouse experience. In my book, however, it's not something that revolutionizes the use of mice.

Price

At the time of writing, I can find the Logitech MX Master 4 with an online price of 999 kroner. That's an increase of a few hundred kroner since we saw the MX Master 3S. Here they carry the new Action Ring and Haptic Feedback

Conclusion

There's a reason the Logitech MX Master series of mice has become as popular as it is. With the MX Master 4, Logitech builds on the strengths that have made previous mice in the series such powerful tools for creatives on a PC.

The new additions like Action Ring and Haptic feedback really support a strong focus on productivity. It takes some getting used to getting the new shortcuts and options programmed into muscle memory, but once it clicks into place, it's like a push in the back to your workflow. As long as you use the supported applications, which are currently quite limited.

We land with a final score of 9 and a Great Product Award, for a strong update to a popular series from Logitech.
