Customer Ratings & Reviews

This sounds insane, but this mouse is a GAME CHANGER. The haptic action button lets you change between 6-8 apps seamlessly in seconds. It makes everything you do faster. It’s so good that I bought 2 - one for work and one for home. The haptic feedback makes it even more awesome.

Excellent … the feedback on the buttons is pretty fire … smooth workflow , and custom button assignments for me .. excellent .. I use the haptic button as an Enter button … excellent mouse , excellent battery … excellent aesthetic. If we can make it lighter .. that would be awesome :)

First off I'm in love with how quiet this mouse is, I'm into a more quiet build with my office right now, and this mouse very much fits that esthetic. I also really like the horizontal scroll wheel, I feel like every mouse should have this, and I'm not fond of the 360 scroll wheels out there. I enjoy the feedback on the side of the mouse, I think it's a nice touch, and being able to change the sensitivity of the vibration along with the force required to use the button as a plus. The feedback button where you can have preset keys to do certain things is also really helpful, although I don't use it as much as I should because I have a stream deck. Also if you're sharing your screen, the people watching can see those buttons, so if you're trying to be descrete I wouldn't use the feedback button for that purpose, however that's also a very niche observation. The only slight complain I have is if I'm gaming, which to be fair I shouldn't be using this mouse for gaming but I'm not that competitive so I don't really care, I sometimes get the mouse buttons on the side confused since there's 3 buttons. Other than that, the mouse is great for video timeline editing, which is what I really bought it for.

The MX Master 4 delivers exceptional comfort, and customizable controls that elevate everyday productivity. The best things about are: Build quality, battery life, and its multi-device support.

Very nice mouse. Good for big hands. The battery seems to last a long time. Great for laptop.

Great mouse. Feels wonderful in the hand. The ultimate productivity mouse.

Ergonomic and smooth function with great battery life

Excellent ergonomics. Battery life great sufficient for multiple days of work. You can customize the buttons and decrease use of keyboard signifcantly

The action ring is a nice addition. The rest of the mouse works as advertized.

Coming from an MX Master 3s, the ergonomics have been vastly improved, and the haptic feedback makes for a solid re-design.

Best mouse for non-gamers! Excellent for regular computer tasks. Shortcut buttons on the mouse really make all features really useful!

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.

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

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.

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

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

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.
