This wireless mouse uses Targus's "BlueTrace" sensor technology, an enhanced optical tracking method designed to track reliably across a wider range of surfaces than a standard optical mouse, including glass or glossy desks that trip up cheaper sensors, without needing a proper mousepad. It connects wirelessly via a small USB receiver rather than Bluetooth, so it works the moment the receiver is plugged in with no pairing menu required, and is a standard three-to-four-button design (left, right, scroll wheel/click) intended for everyday laptop and desktop use rather than gaming. Finished in black to match most laptops.
