Until now, some of Logitech's better mousing features, particularly its extra-small Nano Receiver and its free-spinning metal scroll wheel, have been limited to high-end devices; outside of the MX 620, none of its previous devices have come with either for less than $70. The V550 Nano aims to solve that problem by bringing both features to a $60 notebook mouse and adds a unique notebook-mountable clip at the same time. It succeeds in lowering the cost, but our full review determines whether that comes at the expense of design.
