Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, Black

I've been using the MX Master 4 (Pale Gray) and so far it's been a great experience with no issues to report. Logitech really nailed the form factor—it's comfortable for long sessions and fits naturally in hand. The weight feels well-balanced, not too heavy but still substantial enough to feel premium and controlled. One of the biggest improvements for me is the battery life. Compared to my original MX Master, the charge interval is noticeably better, which makes day-to-day use more convenient and low-maintenance. Overall, it feels like a refined version of an already solid lineup. If you're familiar with the MX series, this is a smooth upgrade.

This is a wonderful ergonomic mouse and definitely worth the price. The haptic feedback works really well and gives a reassuring feel when the mouse connects to the device. The buttons are soft, responsive, and comfortable to use. Still more to explore. The scrolling experience is excellent—very smooth and extremely fast, which is especially helpful while working with large documents. The side scroll feature is another great addition, making it easy to navigate Excel sheets horizontally from left to right. Overall, this mouse improves productivity and comfort during daily use. Thanks to Logitech for creating such a great product!

The mouse is famous for a reason, all the features are amazing. My favorite thing about the mx4 is how comfortable it is over extended work sessions. The "click" is the best feeling. Its a beautiful mouse and the new materials stay clean for wayyyyy longer and are way easier to clean. I got the non-mac version to get the USB C dongle and it works flawlessly on my Mac Mini M4 with the logi+ app.

The Logitech MX Master 4 is outstanding. The ergonomic design is extremely comfortable for long work sessions, and the precision and responsiveness are top-notch. The scroll wheel is smooth and versatile, and the customizable buttons significantly improve productivity. The Pale Gray finish looks clean and premium, and the battery life is excellent. Overall, this is a high-quality mouse that's well worth the investment, especially for office and professional use. Highly recommended.

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. ⭐⭐⭐⭐⭐

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!

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).

The MX Master 4 feels solid and comfortable in my hand. I appreciate the context-sensitive controls. Also, I'm glad for the included dedicated dongle. I tried connecting through both standard BlueTooth and the dedicated dongle. I liked the flexiibility of using the BlueTooth controls, but I found that the dongle gave me faster response -- probably because of other device loading through my integrated BlueTooth.

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 love the new style, with the haptic feedback. Still getting used to the actions ring, not very useful in my opinion/use cases. But I love using the side buttons to switch between apps and desktops. Would like to be able to configure the type of haptic feedback for each action, as switching desktops for example has an exagerated feedback, while other things are ok.
