ABOUT MX Master
An instrument of craft mastery
Logitech MX Master resets the bar on performance and precision in a laser mouse.
Connect with up to three computers using the included Logitech Unifying™ receiver or
Bluetooth® Smart wireless technology, and switch among connections with the touch of a
button.
A speed-adaptive scroll wheel automatically switches between two modes: a precise click-to-
click mode and a hyper-fast mode that’s ideal for navigating long documents or web pages. The
unique thumb wheel provides effortless side-to-side scrolling.
The perfectly sculpted body of the mouse supports your hand and wrist in a comfortable, natural
position. Darkfield™ laser tracking gives you flawless control on virtually any surface, including
glass* and other high-gloss materials.
Unlock all the possibilities MX Master offers by installing Logitech Options™ software. In
addition to optimizing the mouse for your operating system, the software lets you customize MX
Master buttons and actions to fit your needs.
Note: Descriptions of features that require installation of Logitech Options software are
shown in blue.
The MX Master mouse charges quickly: 4 minutes powers it for an entire day. A full charge can
last up to 40 days**.
