A star deduction because keyboard nonsensically other key arrangement (arrow keys) and the enclosed "Description" is a joke. I do not know how it creates Logitech in as many languages nothing useful to install the drivers to write / to provide information on how to install when Keyboard already exists. Alone this leaflet would be justified reason for return (eg I found no info for now button on the bottom of the mouse). Multimedia extra buttons are dark gray with dark lettering. Has that come up with a designer for looks? This is counter-productive in normal lighting. Who can not be put off by these two points, gets a good keyboard. Mouse is quite small oops, I got my "compact", but is just good in the hand.
