Update as of 30.1.2012
3 1/2 months I have the mouse now. But you can imagine how many times you have a spare mouse in use. So my rough estimate was less than 10 times in use because I have installed at every workstation anyway a fixed mouse. She was always transported in a padded laptop bag. Although it works in principle yet, but unfortunately without a wheel in the middle. The turns unfortunately only by empty. As I said, no violence or rough treatment. But a Trash. Too Bad.
