I thought a comparative list of advantages and disadvantages of this set of keyboard + mouse and finally I have found no negative not even the price Already once connected we can use what is almost "magical" compared to some computer accessories The keyboard keys are very comfortable flexibility for people like me who do they surf mails and keypad ergonomics was very well adapted to left handed users The most basic mouse is still very nice in hand And best of all the basic settings such sound volume are made directly on the keyboard The next day it seems to have always been, and we wonder how we could use until now the original mouse + keyboard so basic and inflexible An adviser to product for all those who can not (or will not) make a fortune in their PC and want to have all the same user comfort all without fuss to install
