The first time that I had to replace a screen on my daughter's iPhone 6, I had one put on. Once since, she cracked that screen protector which saved the phone screen. So I tried using her phone several times and really thought it was an extension of the screen. Nothing like any other screen protector I had used before. I watched them attach it, and was impressed on how it put the protector exactly in place with that jig. So, when I fell and cracked around the home button of my iPhone 7, I put one on mine. I got one for the iPhone X, and really appreciated the fact that as soon as we removed the plastic protection on the phone, it went right into the jig for the screen protector. I fit perfectly. At this point, I am truly enjoying it.
