My husband just noticed a long crack in it and he didn't drop my phone or mishandled it in anyway! It must've been cracked when he put it on his new phone.
This screen protector fits perfectly, and is as close to invisible as one could hope for.
The phone is every bit as responsive with the protection in place as it is "naked". I just feel so much better knowing that my actual screen won't get scratched or marked up from frequent use.
