Very good ambidextrous mouse, but ...

Being left-handed, I was looking for a versatile and ambidextrous mouse (gaming and office) that I could set up my own way. This mouse performs all these functions very well, and the hand-making is impeccable. By cons, in recent weeks, the wheel starts to make his own and "jump" up regularly when I scrolls down. This is due to the design of the mouse that easily allows dust to set in at the wheel ... eventually I would try dusting with a dry air bomb and hope it fixes the problem.
