Background

Released in 2017, the Logitech MX Master 2S is an ergonomic, premium wireless mouse with a rechargeable battery, launched as the direct successor to 2015's popular MX Master. Compatible with both Windows and macOS, the MX Master 2S supports Logitech Flow, a software that allows the user to move the mouse cursor and copy and paste text, images, and files across three computers. Like its predecessor, the MX Master 2S can connect to devices either via a 2.4 GHz Unifying Receiver or over Bluetooth.

Improving over the original, the 2S offers more sensor performance and longer battery life. The MX Master 2S has since been followed up by the MX Master 3 and MX Master 3S.

The Logitech MX Master 2S can be identified by the model number ("M/N") M-R0066 (or part numbers, "P/N") 910-005131, 910-005139, 910-005839, 910-005965 depending on region, vendor, and color. The model number can be found printed at the top of the mouse's underside. The part number can be found printed on a large sticker on the mouse's underside. The device's serial number is also listed here, labeled "S/N."
