I bought this to replace a different brand of screen protector and I can tell an immediate difference. My phone wouldn't read my thumb print through my old protector. Using this one my phone reads my print 1st try every time. It was also much easier to install. I placed one edge against my phone then it did the rest all by itself, no bubbles. I also am very happy to have the camera protection. My only complaint is that is doesn't fully cover my screen but neither did the other one.
