Pleasing shape and beautiful design - done their job

The Logitech mouse has a wonderful ergonomic shape, so that the hand does not get tired even after prolonged use.
As for the size, I can not agree with the previous speakers. It is larger than the mouse that I had previously in use and is the ridged rubber just perfectly in the hand. (I have no children hands and even if my hands would be greater, which would in my opinion be the case).
Installation was easy, the USB stick is so small that it does not interfere with work, the mouse has a convenient on-off switch and is easy to move (even without a mouse pad).
I am completely satisfied. The matte design contributes to a high-quality appearance. More can not be expected of a laptop mouse. ;-)
