I have this mouse for a few years and I'm very satisfied with it - the naga was too small, but this one is perfect. But in the last few months the left and right click on the wheel scroll stopped working - I still hear the click, but nothing happens. Is there any way to fix it? Also, any idea why the newer versions of logitech MMO mice (like the G702) have less buttons? I really need as many as possible. Any other good alternatives except the Naga out there?
