As with other products in the MX series, each button has a feature and that feature is dependent on the application you are currently in. Within Chrome, the thumb wheel changes tabs; in Word, that wheel now controls zoom; and if you jump into Photoshop, you’re now making precise changes to brush sizes. In Photoshop, the thumb and palm buttons also bring easy gesture controls.
Logitech have improved the scroll wheel from the previous model, which had received some negative feedback. The new MAGSPEED feature on the Master 3’s scroll wheel gives you two modes: Ratchet, for a locked in, line-by-line scroll; and Free-Spin, for when you feel the need for speed – you simply disengage the magnets and scroll 1,000 lines per second.
Battery life remains the same as the previous 2S model – a not-so-shabby 70 hours on a full charge. Impressively, one minute of charging over the included USB C cable will pump a remarkable three hours of life back into the mouse.
Logitech boldly claims the Master 3X to be five times more precise than a ‘basic’ mouse thanks to its Darkfield Tracking. Surprisingly, this was very good and smooth, and you are able to track on virtually any surface – even glass. All of this with a DPI range of 200 to 4,000.
Overall, the MX 3 is a great mouse – wrist-friendly, with tons of features wrapped up in a simple elegant black shell, which is extensively customisable when teamed with Logitech Options. £100 is a lot to ask for a mouse, and personally, while its features justify the steep price, if you are not going to make use of all the features, it may not be your first choice. There are many other productivity-based mice on the market that are considerably cheaper.
