quality mouse

I've been looking forward to a new MX Master for years after my previous finally had had enough. I am very pleased with the new version. Customisation of the action button is quite useful. Can't fault it

Great update

The Good • Deadly Quiet: The clicks are even more hushed than the 3S while maintaining a tactile feel. • Improved Glide: Widened PTFE feet make it feel "lighter" on the desk despite the actual weight increase. • Connectivity: The 2x stronger signal and new USB-C Bolt receiver solve the rare jitter issues of the past. The Not-So-Good • The Weight: At 150g, it’s a "chonker." If you prefer a nimble, light mouse, this isn't it. • Gaming Lag: The 125Hz polling rate is still mediocre for 2026. If you want one mouse for 10 hours of Excel and 2 hours of Call of Duty, the Razer Pro Click V2 is its main rival.

Nice and quiet, with improved button feel and functions

I had two Master 3S mice and replaced them with Master 4's because they were advertised as even quieter, and I've found that to be the case - not as much a leap as from the 3 to the 3S, but still pleasing. I also enjoy the new Gestures button (in front of the Forward/Back pair) and the way the new Action button (replacing the old Gestures button) is much easier to press (a soft press inward rather than an overly firm press downward) and brings up a programmable menu of options. The only mild negative is that it's hard to pick up and relocate without pressing any of the thumb buttons, but I've retrained myself to pick it up with my thumb under the left edge, and I'd rather that than do without the new Actions button.

Excellent piece of equipment

This is a highly responsive and easily programmable mouse, which means that you can not only navigate the screen quickly but also perform loads of frequently used functions through mouse clicks, buttons and wheels. There are many preset functions that you can choose from and it is also possible to add key commands which you have set up in other apps. The new addition to this, the thumb button which is set to open an Actions Ring (also programmable) was overly sensitive for me at first but I have recently found that I can change the sensitivity to 'Firm' which has resolved that problem. Its shape is comfortable and I can work for hours with this mouse. An excellent piece of equipment.

⭐⭐⭐⭐⭐ 5/5 — A Game-Changing Mouse for Productivity

[This review was collected as part of a promotion.] The Logitech MX Master 4 is easily one of the best productivity mice I’ve ever used. From the moment you pick it up, the ergonomic design feels premium and comfortable, especially during long work sessions. The build quality is solid, and the matte graphite finish gives it a sleek, professional look. The standout feature is definitely the MagSpeed scroll wheel—it’s ultra-smooth, fast, and precise. Switching between ratchet and free-spin modes happens automatically, and it makes browsing long documents or spreadsheets effortless. The side scroll wheel is also a huge upgrade for multitasking, especially for video editing, spreadsheets, or timeline controls. Battery life is impressive, lasting weeks on a single charge, and it charges quickly through USB-C. The customisable buttons let you tailor the mouse exactly to your workflow, and the ability to switch between devices with one tap is perfect if you work on multiple screens or systems. Overall, the MX Master 4 is worth every penny. If you value comfort, performance, and productivity, this mouse is a must-have. Highly recommended.

too heavy and low polling rate

it needs more polling rate, needs to be lighter and the side scroll needs to be adjusted so its not easy to accidentally side scroll.

Works great

[This review was collected as part of a promotion.] The Logitech MX Master 4 for business it's great mouse for work. It comes in a nice black box and looks very professional. The mouse feels strong and well made. It fits perfectly in my hand and is very comfortable to use. The scroll wheel is fast and smooth and the extra thumb wheel makes it easy to move sideways in documents. The clicks are quiet, which is great for the office. It connects easily by Bluetooth and works on almost any surface, even glass. The battery lasts long time and it charges very quickly. It takes a little time to learn all the buttons and options but is the best mouse I ever have. Perfect for people who work a lot on computer. It’s fast, comfortable and very high quality. Highly recommend
