Customer Ratings & Reviews

Best in class. Confort, precision, customization. New haptic feedback makes side button more improved. Still very expensive for a a mouse.

Best mouse ever. I've had the MX Series ever since the 2 and Logitech such keeps innovating. The performance is amazing, and the new feature for the thumb button has improved my productivity. If I had a complaint, I'd love better battery life but that's about it. A note about longevity. I won an MX 518 at a conference back in 2003, I didn't retire it until 2018. These things last a LONG time. Invest the money. It will be worth it.

Works amazing at work. Side scroll is amazing and all the keynote i can customize

Great mouse, love the customizable buttons and the ergonomic feel.

This is easily the best mouse I've used. The only thing that I can say negative against it is it's big. It's large, so if you're on the go and want something to throw in your pocket or your bag, it's not the most portable. Otherwise, perfection!

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

I already own a MS Master 3S and I love it. Its at the office. I wanted another one for working from home, but I held off knowing this was coming out. I really enjoy it. It brings all the same stuff as the 3, but less rubber, so it wont start to look terrible after a lot of use. The haptic control panel is also really neat.

What really sets the MX Master 4 apart is its haptic feedback and Actions Ring features. Subtle vibrations enhance interactions like scrolling, shortcuts, and gestures, giving real tactile cues that make complex workflows feel smoother and more intuitive. The customizable Actions Ring (via Logitech Options+) lets you assign app-specific commands without reaching for the keyboard, which can significantly speed up tasks in creative or productivity apps.

Excellent mouse. The previous versions have served me well. This is a nice upgrade. They fixed the major thing with the previous versions, which was a rubber wheel that disintegrated quickly. This one has a nice metal wheel which is nice. The vibration function is not just a gimmick. I kept accidentally hitting the thumb button and launching a built-in menu. Going to the menu and increase decrease the sensitivity and it's okay. It's pretty nice, once you start using it, you'll wonder how you lived without it. Overall, it's an excellent productivity mouse.

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 mouse is an excellent entry point for someone who lives and needs of an efficient lifestyle. This ergonomic mouse is the best tool for that. Living in an industry where there may be a hybrid work-lifestlye. Where we might go to an office, get work done, next day work full-time from home tools like this mouse in particular, when needing the macros so you won't be jumping around tabs, applications, and or taking screenshots fo example, all of that can be done from the palm of your hand (no pun intended). Although I do no feel like that the "tactile" feedback taht you get from pressing the button on the side is a good addition to the mouse it is a love/hate relationship. Until now I've been using this mouse for the past 2 weeks and it checks all of the boxes. For me. There is still room for improvement. Like me, get the whole combo. With the MX Keys. These two together are a beast of their own.

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.

If you use a computer (Mac, Windows, or Linux) in your day-to-day, especially for work, you would benefit *greatly* from this masterpiece. Buttons exactly where you need them. Built in macros. An unholy number of programmable gestures. Instant access to your favorite AI models at the press of a button. Ergonomically comfortable. If you have a Magic Mouse for your Mac and you love it... This will blow it out of the water. There's just no comparison when you take into consideration the number of things this mouse can do and the way it feels in your hand.

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 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 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.

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.

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

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.

I use Macs exclusively for my photo editing, specifically via the full Adobe suite of Lightroom Classic, Photoshop, Premier Pro, etc. This mouse has been a game changer for photo editing especially when compared to using a MagicPad. It’s much more precise and the Adobe apps already take advantage of the mouse’s additional capabilities. This mouse was a big upgrade to my photo and video editing process.
