Easy to set up , easy to use . plug in adapter , remove protective film from mouse & keyboard . that be it . install software to access additional function . as a touch typist , I be concern about adjust to the different keyboard style , but it have take I all of 15 seconds . Sweet . love the mouse , too , although it will take some tweaking of the setting before I stop overshoot the mark . the usb adapter be so tiny that I nearly do not find it hide up in the top , leave corner of the box . have use and be happy with Logitech in the past , and I can see this will be no exception .
