can look very sophisticated. extremely ergonomic. very precise. sampling function excellently on all surfaces that I have tasted. very wide range of accessories. can be programmed class, to individual programs such as Photoshop. Class is also the Application Switcher, which allows a comfortable switch between the open applications. just for photo editing important. pushes very soft on the underground not to rutschig- not "sticky". only the Unifying program did not recognize the mouse, although thick advertised. The only shortcoming.
