The Logitech MX Master Wireless Mouse is designed for revolutionary precision and speed. It features a hand-sculpted, ergonomic shape that supports your hand and wrist in a natural position, offering fine-motion control and a fluid experience with well-positioned buttons and wheels. The mouse utilizes Darkfield Laser tracking, allowing it to track flawlessly on virtually any surface, including glass (with a minimum thickness of 4mm) and high-gloss surfaces. It offers both RF Wireless and Bluetooth connectivity, allowing you to pair up to 3 devices and switch between them with a single button press using Easy Switch technology. The smart speed-adaptive scroll wheel automatically shifts between click-to-click and hyper-fast scrolling, enabling faster and easier navigation through long documents and web pages. A unique thumb wheel provides side-to-side scrolling capabilities, which can be further customized with Logitech Options software. The mouse is rechargeable via a micro-USB cable, offering up to 40 days of battery life on a full charge, with a quick 4-minute charge providing enough power for a full day's use. The movement resolution is 1000 DPI, and it has 7 pressed buttons. It is optimized for Windows and Mac computers.
