The V550 Nano features a Clip-and-Go dock for attaching the V550 Nano to your laptop. This dock is a peg with an adhesive back that sticks to the outside of your laptop. The mouse itself has a hole on the underside that snaps on to the Clip-and-Go peg. Logitech includes a Clip-and-Go removal tool with the mouse, which you can use to remove the peg from your laptop.
The mouse uses the 2.4GHz wireless technology, not Bluetooth. Logitech includes a tiny USB transmitter, which can be stored in a compartment inside the mouse.
Logitech claims that a pair of AA batteries will provide 18 months of use for the mouse. The V550 Nano weighs 4.23 ounces (with batteries) and measures 3.98 by 2.28 by 1.34 inches.
The V550 Nano requires Mac X 10.3 or later and a USB port. The mouse sells for $60 and comes with a 3-year limited warranty.
