A great mastery

Logitech Revolution ... ... In practice it is not necessarily obvious the first time, and in fact the first days either ... Just for him to come back to a device "almost" standard (a V400 from the same manufacturer) to see THE revolution = the dial.

Under MSWord, a 300-page document is over in two "rolls" and the XP driver functions and buttons become natural. Ah direct zoom in photo editing and click on the roulette wheel!

But this mouse loses 1 star for the software driver that consumes excessive resources, freewheel knob that releases only from below, and no carrying case.

Note that the manufacturer's website gives the trick to use a Logitech keyboard first generation with this mouse, in view of the driver incompatibility.
