Instructions and video were for a different model of phone which made it a bit hard to follow. There are a lot of steps and if you get 1 wrong it causes all kinds of problems. Because I missed a step I basically had to take all of the film off of the screen protector and manually align and place it myself. This caused it not to be 100% straight which has caused the edges to role and collect dust. It's been on over a month now and hasn't caused any problems. As long as you can get it on right it's a decent protector.
