You'll notice the left spot is almost completely barren of any copper coloring due to it rubbing off on my thumb, and the copper on the right side underneath the right-click button is fading onto my ring finger and a bit of my pinky

The main reason I got this for my fiance was because it had nice affects, the dpi, and number one was that it was going to be a "Noiseless Click" but it isn't whatsoever

My only suggestion for improvement would be silent clicking, but aside from that, the clicks are solid and very responsive
