This screen protector has just saved my iPhone 5S from a smashed screen! I was getting a cup out from a high kitchen cupboard when I dislodged an old and heavy toast rack - with sharp edges - that fell about 1.5m onto the screen of my phone. You can perhaps see what happened in the photo - the screen protector took the impact, was punctured, and seems to have directed the force sideways, leaving the screen totally unmarked! Brilliant. Just fitted another from the pack of three - and recommend using the "trick" of laying the complete protector on the screen, aligning it carefully, and then taping it with paper tape down one side onto the phone body. Then you can hinge the protector up, take off the covering from the screen side, and hinge it down into perfect place. So easy. Good product, saves you loads of money!!
