The infamous Logitech MX Master 2S Prime Day deal is gone - long live the MX Master 3S
The student becomes the master.

For what felt like ages, we had a routine around these parts for Prime Day. Prime Day comes, the Logitech MX Master 2S would go on sale, I'd write a deal up, and post. And that went on for a long time. But, this time, it wasn't there.
It appears that with the releases of the MX Master 4 last week, something changed. Now the newer MX Master 3S is the old dog that gets discounted, although we aren't at the £40 stage quite yet. For Prime Day, the MX Master 3S is down to £80 from Amazon, which is a small but handy discount on one of the best office mice in 2025.

The MX Master 3S isn't much of a cosmetic upgrade on its predecessor, sticking with a tried-and-tested design withs its comfortable frame and rubberised soft-touch coating. Its metal scroll wheel offers a precise line-by-line mode with notched, tactile feedback, as well as a smooth-gliding free-scrolling mode ideal for zooming through long documents or web pages, while the main mouse buttons are dampened, meaning they're an awful lot quieter than the older MX Master 3.
Its sensor has also seen its sensitivity double to 8000 DPI. This is plenty for office duties, and makes the MX Master 3S an absolute joy to use. With this in mind, though, this isn't a mouse designed for more than office duties, given that sensitivity and higher weight. For the tasks it's designed for though, it shines, especially when paired with the powerful Logi Options+ software suite. It connects via Bluetooth for this 'Amazon' edition of the unit. Pairing is easy, and it works on up to 3 devices. The MX Master 3S also retains the same 70 days of battery life, too, giving you some solid endurance in between charges.
The MX Master 3S is a mouse I can speak of especially highly, and if you're someone who wants to grab an excellent office mouse to use on all manner of devices, this is one of the best you can get, especially with that Prime Day discount in mind.
