Supermaus defective except small.

Actually my mouse has super fallen, fits comfortably in your hand, has super settings and is suitable for both right- and left-handers.
Even during long sessions I found the mouse never uncomfortable or anything. Well, I also found that the G-keys are mounted on top and not on the side, until here it would have been of me 5 stars.
However, it has now loosened the top of the mouse after a year of intensive use, which is shaking now and creaks.
Furthermore started my right mouse button recently to "spin", that is, when I will once it press the click either not wargenommen or equal to double, triple or quadruple. which is pretty annoying on both the desktop as well as during gaming.
I do not know if that's for me an isolated case or whether the more often occurs in this model ... Too bad, otherwise I would have gladly given 5 stars.
