I set this in place to protect keyboard . it will do that . 2 fatal flaw that keep it from be use . 1 . lock in heat that would otherwise escape through space around key edge . heat kill electronics . I do not want to speed up the process . 2 . Blocks light for light keyboard . nice feature on MacBook pro , take away with use of this protector . on balance , it apply easily and fit well . Easy to remove . final thought : I be more concern with my Mac 's lifespan than I be with protect the well make key from get debris fall through . recommend you just do not eat or drink around any keyboard , and ESPECIALLY not around a laptop . save you money here .
