The Logitech MX Anywhere 2S Wireless Mobile Mouse has the Logitech Flow feature which allows you to control up to three computers using this one Logitech mouse, enabling seamless text, image, and file transfer between devices. Logitech Options software is required for this feature, which can be downloaded for free (only for Mac or Windows). Darkfield High Precision Tracking provides precise control on almost any surface, including glass with a minimum thickness of 4mm and up to 4,000 dpi. This ergonomically designed mobile mouse fits comfortably in your hand and provides you with the control you need, whether at home, work, or on the go. With just a three-minute charge via micro-USB, you can get enough power to last a whole day of use. A full charge on the Logitech mouse can last up to 70 consecutive days.
