Microsoft Arc Mouse Black

Portable design: The Arc Mouse snaps flat to power down, allowing it to slip easily into a pocket or bag without the bulk of a traditional mouse. It powers on when bent into its curved shape. Intuitive scrolling: Instead of a traditional scroll wheel, it features a full-plane touch-sensitive scroll surface for both vertical and horizontal scrolling. BlueTrack Technology: The mouse uses Microsoft's proprietary tracking technology, which works on a wide variety of surfaces. Wireless connectivity: It connects wirelessly via Bluetooth 4.0 or higher, eliminating the need for a USB receiver. Ambidextrous: The design is symmetrical and can be used comfortably by both right and left-handed users.
