There must be massive differences in clear button protectors between manufacturers. I find it hard to believe that anyone could say this looks bad compared to a big lollipop rail which completely covers the artwork. Even with the camera flash on it, it's still hardly noticeable in my opinion. Just a slight darkening of the colours underneath of it. I say if the damage is already done then go ahead and cover it with the lollipop rails but if not then try and get some nice clear protectors to enjoy the artwork. Unfortunately I'm not sure where these protectors came from since they were on when I bought the machine :-/.
