Logitech MX Master 4 Ergonomic Wireless Mouse Pale Gray 910-007559

I use the MX Master 4 on Linux over Bluetooth. It's very responsive and the scroll wheels are my favorite features. I use the thumb wheel to scroll left/right (such as when working in a spreadsheet) and I click the little top button to scroll through something line-by-line (like code) or click it again to go back to a "smooth" scrolling mode (easier for web pages and documents).

This was an upgrade to my MX Master 3S which I used for years. The Master 4 fits my hand just as well and the haptic feedback is a nice, usable upgrade. The biggest difference is that the vertical scroll wheel is set back just a bit closer to the center of the mouse making it more comfortable to use on a daily basis. Excellent build quality as expected and a joy to use!

The feel of the grip and button location is different than the MX Master 3 that I used for years. Button tactile response is good. Haptic feedback setting on low is plenty for daily work. Actions ring takes some getting used to but customization is good and helps make it useful. USB DONGLE - UGH, laptops put less USB ports in and Logitech still requires the user to connect with the dongle to get all the features... and of course the company keyboard uses a different dongle than the mouse...

I have never used a mouse like the MX Master 4 before, and at this point, I only want to use this mouse moving forward. Hands down, this is the best accessory I've ever purchased for my MacBook Pro. The comfort, precision, customization, and overall feel are on a completely different level from any other mouse I've owned. It fits perfectly in my hand and makes long workdays significantly more comfortable. What really says it all is this: when I'm traveling and not using my normal desk setup, I miss this mouse more than I miss my second monitor. That should tell you everything you need to know. I can work without the extra screen, but I genuinely notice the difference when I don't have my MX Master 4 with me. Whether I'm managing spreadsheets, answering emails, building proposals, or simply navigating between applications, this mouse has become an essential part of my workflow. The programmable buttons and scrolling experience save time every single day. If you're on the fence, stop thinking about it and buy one. It's one of those products that immediately becomes part of your daily routine, and you'll wonder how you ever worked without it. 5 out of 5 stars. Absolutely worth every penny. ⭐⭐⭐⭐⭐

no onboard memory. understandable because companies sometimes don’t allow usb drives. but this kills all the gestures and programmability of the haptic and action buttons

I am very happy with this purchase. I originally hated the idea of a large mouse, but when I started getting heavy into Excel tasks at work, I knew I wanted to upgrade my cheap mouse. I figured I would try this along with the MX Keys S keyboard, and it's the best.

I have never been so excited to use my mouse before

The most amazing mouse I have ever used. Smoothest scroll. Smoothest glide across the desk. The haptics are truly impressive and the action ring is just wonderful

Love the feel and response of the mouse. Amazingly quiet clicking.

ergonomic, and small enough to carry in your bag yea

I used the Performance MX mouse for years and was happy with its quality and design. After upgrading I’m fully convinced that the hype is real. This was the best upgrade that I should’ve made when this new model was released!

Logitech decided to use cheaper materials compared to MX Master 3S. It’s now just super cheap plastic, like you get with the free mouses when you buy a computer. A real downgrade build quality wise compared to the prior master series mouse. Disappointed.

great product. I use a mouse about 10-12 hrs per day and these last for 3-4 years. I am on my 3rd version and each iteration has seen real improvements. I've not seen or used a better mouse in over 40 years of professional computer, engineering and IT use.

this is a mush have device. Exact ergonomic for my hand. Perfect buttons and functions.

I'm very pleased with the MX Master 4, the 4th mouse in the series I have owned. It operates smoothly and as the previous model have, it fits comfortably in my hand. What I'm most interested in see is how the finish material that my hand contacts "stands up" to long term use. Hopefully it is more robust than earlier models. I'm also interested to try out the enhanced mechanism to set and select program actions more efficiently.

Feels great, looks great, clicks great. Made of really quality materials too. The horizontal scroll wheel is fun to fidget with, functionality aside. My only gripe with it is the low polling rate, 125 Hz. I know this is better for battery life, but I'd at least like to change it so that I could use it for gaming if I really wanted to. Other than that, fantastic mouse.

I finally replaced my MX master with the MX Master 4 after the rechargeable battery gave out. I like almost everything about the Master 4, however I had to disable the new thumb button because it is so sensitive that I kept on pressing it by mistake. Unfortunate since on my MX Master I used that button as Ctrl + a (select all).

The mouse fits my hand well and the cover does not get sticky. The only issue I had was that the mouse was used by someone else before. As with the keyboard I purchased. The second one that was sent to me did not have as much wear as the first one so I kept it. It is a real hassle to return and reorder something with Logitech.

Good mouse but much heavier than the previous Lift I had. And also wish it was the handshake grip.

Fantastic improvement over 3 or 3S. Way better material!
