Got the mouse to play not worried because I really come to rarely :-( But for operation in office, it is also an improvement in any case. It is very comfortable to hold and is fully functional to date any surface. The buttons on the side to navigate through the Internet or in the folder structure are in the right place and easy and precise to operate. Lights she had for me not have to, but it läst indeed disable ;-) Even without driver it is good to use when you have fast times.
I'm curious to life when there found no Rasch busbars I am fully satisfied on.
