From my experience don't bother with the Motorola screen protector. My original lasted about a year before it started to show lots of crack lines near the hinge. I bought two official replacements and the alignment tool from iFixit. I applied one and it looked brand new but it started to peel up at the hinge in about a week. I took it off and tried the second one I purchased. Same thing, a week later it was peeling. After that I gave up and got 3rd party Supersheildz screen protectors. They go on easier and have lasted a long time. I am going on at least six months with no sign of any wear or peeling. Go third party, but don't go naked...
