Hello, as you can see in the title that my mouse has a dark spots which cant be removed. the spot is more darker than the original color, it even reflects a bit. This also happened to my grey mouse that had big black spots in the left and right click i thought it was the paint getting screwed but the razer mouse which is black also has one and i just realized that it also has the 2 big darker spots in left and right? is it my fingers? whats happening?
