although it comes with some tools to help line up the screen protector, it is still hard to apply. instructions were clear but the lining tool does not help much. once applied, there are small bubbles on the screen protector that does not go away. it cannot be smudge off and i have been waiting for a few days for it to disappear. tried both protectors and failed. only good thing about it is that it it seems to stick on really well but it just looks ugly with random bubbles all over.
