Well guys i have ordered a set of circle pad grips, and some peope on amazon in the reviews said that it broke/cracked their 3ds screen? how does that even happen? supposedly if you keep them on it ,it then might damage the screen? well, it would be really hassly to keep pulling it off it, so i would like to ask if anyone has been using these >>>> http://www.amazon.com/Circle-Pad-Co...qid=1458815305&sr=8-1&keywords=3ds+thumb+grip <<<< and like do you keep them on and close the lid and it does not damage screen or anything ? thanks in advance!
