Who needs a mouse herkömlische

I have quite a few years a Marble mouse and can only say good as it gets. It is very space-saving funktionel, practical and easy on the wrist. I always wonder I'm the only one in my circle of friends one has. They can be found in stores hardly really a pity. People do not know what they're missing a normal mouse is no longer my house unless it has 2 legs. ;-)
