I will give it 5 stars and explain exactly what is happening with this screen protector. Indeed, it does not fully cover the screen. It leaves a very small gap around it, but in combination with the case, it is not that serious. I had a similar (if not the same) screen protector for two years, again with the same gap around it. I always have the black case that came with the packaging applied to my phone since I bought it. So, having this screen protector and the "factory" case, I believe there is no danger. It has fallen countless times for me, only slightly cracking the glass in some areas and getting damaged at the corners, but the screen did not suffer anything even though there was this small gap around it because I believe the case also protects it by embracing the edges. Now, it is also a matter of luck if in that specific millimeter that is uncovered, it can break because, for example, there is a small pebble on the ground that does the job. However, I repeat that with the case on top, I consider it highly unlikely. Finally, I am sure that if the screen protector was bigger and covered the entire screen from edge to edge, there would be no chance for the case to fit properly. Therefore, this screen protector is very good for its price, easy to apply, and seems to be of good quality. Choose it especially if you want something that fits well in combination with the case.
