I didn't have any problems putting my screen protector on. It came with an alcohol wipe to completely clean off your screen and a little cloth. I did notice once I got it on, there was a little nick in it so it had a little bubble. After a few days, I noticed it was starting to come up a little around the edges. This isn't a huge deal right now, since it is a glass screen so it is still flat and doesn't catch on anything. I plan on keeping it on until it gets dirty under it where it was sticky.
Overall, it's a great screen protector. I would like it a bit more if it had stayed sticky around the edges. I don't have any scratches on it at all even though I keep my phone in my pocket. It's a thick, sturdy screen protector.
