As stylish as the SureTrack™ Any Surface Bluetooth® Mouse is, what really sets it apart is the technology inside. The high-definition laser sensor allows it to track anywhere you work—even on glass. What’s more, the SureTrack Mouse connects to your Ultrabook®, MacBook Air®, Chromebook™ or laptop without monopolizing a valuable USB port because it connects via Bluetooth®. For laptops without Bluetooth, users can connect via a Bluetooth 4 dongle (not included).
