I used these for the entire life of my iPhone 5C. They are a little thicker than most screen protectors and take some getting used to. The edges for some reason always pulled up on mine, and I actually had one roll up completely when I put my phone in my pocket one day. They say they will replace it but you have to not only hang on to the bad screen protector, but also the receipt. Being a college student and always on the go and moving apartments, I was never able to do those things, so it was always money wasted for me. I stick with cheaper alternatives now and just throw them away when it's time.
