i love my candyshell, but the screen protector that came with it got scratched up pretty quick. it is my understanding that the zagg is resistant to scratches and therefore might be better suited for me. plus with the lifetime replacement, i feel like it's a pretty safe investment. my question is will the zagg invisible shield work well with a speck candyshell? i'd like to know if it is known to pull up the corners or anything like that. i plan on spending a good amount of time installing the zagg, i would hate for it to be ruined after a few installations/removals of the candyshell case.
