I have GS-501 mouse that I like very much. Unfortunatelly, the left mouse button does not work well anymore. Sometimes clicks twice, sometimes does not click at all. Since the warrany is already over, I thought I could try to fix/replace the button under it by myself. I checked the back of the mouse but I could not figure out how can I even take it apart. Could someone please tell me if what I want is possible? I know the easiest would be to buy another mouse, but only the left mouse button that does not work, if it can be fixed easily, it would not make sense to buy another mouse.
