At first glance, Logitech’s latest mice—the MX Master 2S and the MX Anywhere 2S—are a typical incremental upgrade. They feature an improved “Darkfield” optical sensor, which tracks on most surfaces, including glass, and are more accurate thanks to a jump from 1,600 DPI to a user-adjustable 4,000 DPI. The sensor is more power efficient too, with battery life now rated for up to 70 days based on eight hours of daily use. Unlike Apple’s obtuse Magic Mouse, when the battery does run out, there’s a micro-USB socket positioned at the front, which allows you to keep clicking while charging.
The larger MX Master 2S, which replaces the MX Master, sits at the top of Logitech’s non-gaming lineup, retailing at a substantial £90/$100 (buy here). Like its predecessor, the MX Master 2S is a large mouse with a prominent thumb rest and tall stature that is extremely comfortable, so long as you’re right handed.
The sweeping curve of the older Performance Mouse MX that angled the mouse ever so slightly to the right has been softened, resulting in a more natural feel. Meanwhile, new buttons have been added, including a thumb wheel and a button under the thumb rest, which allows you to replicate touchpad gestures on a Mac or PC. Naturally, all the buttons are completely customisable.
