Unfortunately, the alignment is done by eye, resulting in it not being perfect. It sticks well and without bubbles, but I have the feeling that at the edges, around the perimeter, it doesn't stick strongly, and that's because it left small marks if someone looks closely. So it might come off faster. Let's see how long it will last. Nevertheless, its major drawback is that it doesn't have a case for centered placement. Also expensive (since the others that are 2 cost less than 17 euros). I have bought countless screen protectors, and the Spigen ones are the best. However, I will not buy this model again...
