Customer Ratings & Reviews

this mouse was very easy to hook up and has lots of good features.

Upgraded from my MX3 and it is a noticable difference! The build quality feels higher and the actions ring is a game changer. Haptic feedback is good and consistent. However if you have smaller hands it may feel harder to reach the button in front of the volume buttons. Nonetheless, a great Logitech mouse!

The MX Master 4 earns its 5‑star rating by refining everything that made the 3S great. It feels excellent in the hand, with a shape that supports long work sessions without strain. The new Action Button is a meaningful upgrade—more intuitive and more useful than the gesture controls on the 3S—making multitasking smoother and faster. Battery life remains outstanding, easily lasting through heavy daily use without becoming something you need to think about. Now it is most definitely not as responsive as a gaming mouse. However, if you want a mouse that improves comfort, control, and workflow efficiency, this one delivers exactly that.

I bought this along with the keyboard in the same series (MX4). The customization features have me in aw for a Logitech product. If you're a digital creator or editor, this is for you for sure. The ergonomics are good for small hands as well. The clicks of the buttons are super quite. It even has a haptic feedback feature for one of the side buttons. The 'circles' feature is pretty awesome and customizable too. 10/10 would def recommend.

This mouse is an improvement upon the MX 3 for sure. Just as smooth with its tracking as its predecessors, the feel of the mouse has improved with the haptic feedback of the thumb spot. The use of the gestures is also easier as the button is closer to the body of the mouse rather than the edge. Great purchase overall. Now if it wasn't as expensive I might buy more.

I mean, it's more of the same. I can't complain but they're not really breaking the mold here. I get mouse lag once in a while. At least it's not made out of that rubber that gets slimy within a year. I haven't found an alternative that lasts this long on battery. Only reason I haven't jumped to a different brand. If you need a productivity mouse, this is your best option. And they charge accordingly.

This a great product. I think the length of my fingers does exactly match the curve of the ergo design, thus, it seems a little conscious effort on my end to stretch my fingers... it's a little bit heavier as well.. but overall, it is really a great product with great features. I'd still recommend it.

This is my first MX Master series and from my use with it, I don't see myself ever switching to anything else. The comfort of the mouse and additional inputs make this mouse perfect for my daily work. The side scroll wheel makes searching excel files a breeze and the additional haptic button adds infinite possibilities for more buttons as my workflow needs.

Love this mouse ! Super easy to connect and can be used on multiple machines with the help of a button click . Slick design and very good overall mouse .

Logitech mouse, all I say is a great mouse and never let me down / Logitech been around for many year they make great stuff for me I never had issues. like I said shop around for deal!!!!!!.

Love this mouse. The scrolling feels like it is part of my hand and the extra buttons really take things to another level. Being able to push the back button with my thumb is a game changer. If you are thinking about it, just buy it. You will not be disappointed

It gets the job done. Ergonomic and smooth, works great on a macbook pro.

Very happy with this purchase, the infinity scroll is awesome and the clicks are pretty quiet compared to most mice.

I upgraded from the MX Master 3. I do like the how they changed from the rubber material to the plastic it be easier to keep clean. The action button is a nice addition, it its nice have an additional 8 shortcuts. I do prefer the clicky sound for my MX 3, this one quieter when comes to clicking.

I've been a user of the MX master series for years for my work, and this is a great successor to an overall excellent product line. A little bit expensive but worth it in my opinion.

Never spent up on a higher quality mouse until now. Transitions quickly between computers for home/work use. The Action Ring makes daily use of apps incredibly efficient.

Excellent The ability to push a button on the mouse to copy whatever is hi-lited on the screen is great. Or to open a folder or file without having to scroll through things is time saving.

The Mx 4 mouse is an exceptional tool for enhancing productivity. Its ergonomic design ensures comfortable use during extended work sessions. Advanced features facilitate seamless multitasking and efficient workflow management. This mouse truly stands out for its ability to optimize how we work.

Upgraded from and mx 2. This version solves many of the issues I had with the older gen. Feels good in the hands, haptics are eh, could live without it, but the rest of the ergonomics are great, a big one being the thumb scroll, much easier to engage with.

This is a great product, feels good at scrolling and moving through different surfaces, also what I really like is the long last rechargeable battery that contains
