After many teases and leaks, Logitech has finally unveiled the MX Master 4, its flagship productivity mouse aimed at making your job easier. It arrives three years after the previous model, the MX Master 3S, and comes packing some upgrades and one unique feature. MX Master 4 is all about workElsewhere, its switch clicks are supposed to be 90% quieter than the MX Master 3, while the Darkfield sensor and MagSpeed wheel remain mostly unchanged. The Logitech MX Master 4 is available in four colourways: Pale Grey, Graphite, Space Black, and White Silver, with the latter exclusive to the MX Master 4 for Mac model. Having only just launched elsewhere in the world, it’ll probably be a while before the Master 4 reaches SA.
