Logitech MX Master Wireless Mouse, Bluetooth or 2.4 GHz

A number of interesting features such as the presence of two scroll wheels and the Darkfield laser scanning make it unique. Thanks to Easy Switch technology, you can pair up to three devices and switch between them at the touch of a button. Thanks to its curved shape and soft side surfaces, the mouse in standard size is easy to hold even after hours of use. The carefully thought-out shape, adapted for right-handers, guides your hand into the optimal natural position. Optical and classical laser mice calculate mouse movements with the help of nonbends in the scanned surface. Therefore, they are usually overwhelmed with mirror-smooth surfaces. The MX Master solves this problem with Darkfield-Tracking, which detects microscopically small surface structures and compiles them in a map. The result is greater precision on more surfaces - even glass and high-gloss surfaces. The classic scroll wheel between the two main buttons has an automatic speed adjustment that switches between fast and precise scrolling. Scroll through long web pages and documents quickly and easily. The thumbwheel also provides you with a second scroll wheel, which is responsible for horizontal scrolling as standard. Customize the navigation experience with Logitech Options software. You can connect the mouse either via Bluetooth Smart or via Unifying receiver. Up to six compatible devices can be connected to the same receiver and thus occupy only a single USB port. The integrated lithium polymer battery can be charged with the supplied Micro-USB cable. A full charge lasts up to 40 days at 6 hours of office use per day. With a charging time of only four minutes, you can use the mouse for a whole day.
