Bought this screen protector for a friend with the S5 and it works great. He is very busy and his phone gets knocked around sometimes so he is always in need of a screen protectore. He told me 2 days after he put this one on he dropped his phone out of the truck and onto a rock, he was sure his screen would be broken or at the very least the protector. But he was pleasantly surprised to find his phone was good and nothing was broken.
