Logitech MX Master 4, Ergonomic Wireless Mouse with Advanced Performance Haptic Feedback, Ultra-Fast Scrolling, USB-C Charging, Bluetooth, Windows, MacOS - Graphite

A great gaming device delivers more than just power; it creates immersion. From smooth, lag-free performance to stunning graphics and responsive controls, every detail works together to pull you deeper into the game. Whether you're battling online, exploring open worlds, or competing at a high level, a reliable system ensures you stay focused without interruptions.

I recently picked up the Logitech MX Master 4 - Graphite, and overall it's been a solid upgrade for both work and everyday use. The ergonomics are excellent—it fits comfortably in the hand even during long sessions, and the thumb rest makes a noticeable difference. The scroll wheel is one of the standout features. Switching between ratchet and free-spin modes is smooth and intuitive, making it great for everything from precise edits to quickly flying through long documents. I also use the side wheel for volume control, and it's very precise—honestly one of my favorite features. Battery life has been impressive as well, lasting well over a month on a single charge with regular use. The ability to connect to multiple devices and switch between them seamlessly is another big plus, especially if you're juggling a work computer and a personal one. I find the weight to be just right, and overall the build quality feels premium. It's not the cheapest option out there, but if you value comfort and productivity features, it's well worth it.

I have used various Logitech products, and I am happy to say this one didn't disappoint. Setting up on my Mac was easy using a Type-C receiver. Since I like to protect my devices, I purchased a hard mouse case, and have been enjoying using it. Thanks to the Logi Options+ app, making things easier.

More than just a mouse, this device can also replace a hardware KVM with the use of a Logi Bolt receiver. I was contemplating buying a different mouse, but when I found out that I could use this and a MX Mechanical keyboard on the same Logi Bolt Receiver, my need for a KVM disappeared. I truly enjoy the ease in which this mouse connects to the Bolt Receiver, and how easy it is to go between computers. This capability really needs to be highlighted more IMHO. I also like how we can set up the Easy-Switch with the press of a button on the underside of the mouse, or use a keyboard shortcut to transition between different computers. For my use-case, I have a streaming computer and a gaming computer, and this functionality saved my sanity and removed the need for an additional keyboard and mouse setup. I have been using this mouse for more than a month on a single charge, and the battery indicator states the mouse is at 85% now.

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.

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).

I switched to MX Master 4 from the 3s due to click button problem. Comparing to the 3s, 4 is heavier. The material is also more desirable for me as I don't really like rubber-stick-ness in my hand. Controling is much better with weight. I am in academic, so heavier the better control. Short key buttons are also convenient.

As a previous user of the MX Master 3S, I can confidently say that the MX Master 4 is on a whole different level. I am extremely satisfied with this purchase! Premium Innovation: The new haptic feedback system gives a fantastic tactile response that makes scrolling and navigating intuitive. Actions Ring: This new button feature is a game-changer, giving instant access to shortcuts directly at your cursor and saving massive amounts of time. Superior Build: The materials feel much more premium and solid in the hand compared to older generations. It is smooth, whisper-quiet, and provides the ultimate navigation experience. 100% recommended for any professional!

I have been using Logitech hardware for years now, and I have never been disappointed. Battery life is exceptional, ease of use is outstanding. HOWEVER, I wanted to give this product a 5, but there's one annoying feature that keeps me from doing so. The thumb click for the action ring drives me nuts. I use this mouse for gaming as well, and every now and then I press too hard on the "pad" and the ring appears and makes me lose my place in the game. I have turned down the sensitivity, but it still triggers. I wish I could disable it altogether, but I have been told it can't be done.

This is a great mouse with one flaw that made me return it. The ergonomics hurt my wrist. I had the MX master 3 before this and loved that mouse. Everything about this is a welcome upgrade, except the angle that it turns my wrist. The new design levels out the angle that your wrist holds the mouse so that it's more parallel with your work surface. It hurt so much I had to return it.
