DESC: The V550 Nano Cordless Laser Mouse from Logitech® is an ideal input accessory for people who are always on the go. This cordless mouse features a Clip-and-Go dock to clip itself to any laptop so you can forget about carrying it separately. Its Plug-and-Forget receiver is so small that it is hardly noticeable but still the mouse is up and running. When not in use you can store the receiver inside the mouse. A long battery life of up to 18 months eliminates the need for frequent battery changes.
