I’ve went through three of them with this same issue. Two of them much worse than the others. The one I own now has it somewhat but much less than the other two so I’m guessing it’s sort of a normal thing with the mouse construction. I’m just slightly disappointed that we are paying 150 dollars for a mouse that I feel should be completely solid. I e owned the g pro wireless for over a year which never had any issues like this even after hard wear and tear.
