The Logitech V550 Nano Cordless Laser Mouse for Notebooks is certainly a sleek looking mouse. It features a chrome-outlined scroll wheel and a button that performs window toggling called Document Flip. A thin line divides the two mouse buttons. The USB receiver is very miniscule, protruding only a quarter of an inch when inserted into the port. The most unique feature of the V550 Nano is the docking feature called Clip-and-Go. The Clip-and-Go gives the V550 Nano a docking area to avoid losing it in a cluttered desk. The reviewer noted that using the V550 Nano felt good for a while, but became uncomfortable after a few hours of use. The scroll wheel was impressive, providing quick and smooth response on vertical scrolls. Both the mouse buttons were very responsive but not overly sensitive. For long computing sessions and for frequent travelers, you might want to look for a cordless mouse elsewhere. Otherwise, the excellent scroll response and minimalist design, coupled with the unique Clip-and-Go feature makes the Logitech V550 Nano Cordless Laser Mouse for Notebooks a strong option.
