I bought this for anti-glare and it solved this problem on a Toshiba Satellite laptop with a 15.4 inch screen of "bubbles" between the protective film and the screen which are actually little specks of dust.I've taken them off a couple of times and used some tape and while I was able to improve some areas I ran into the same problem in other areas someone else said I would recommend making sure the screen is flat and then moving from side to side instead of also opening up and down I didn't do that and my problem started with the protective film znul for the bottom panel so I have one on top small gap left. I consider the first sheet app part of my earning curve and if I ever install the second and the experience is better I will rank up. For now I'm disappointed with the looks but more than satisfied with the glare elimination provided by the LCD screen. I am sitting in the room across from my wife who is using a laptop and I can see every little imperfection from the viewing angle. She can't see most problems, so it may be a while before I try a second protector. I'll also make sure I have a completely black screen next time, and with a few cats in the household with nothing floating in the air it's hard to get rid of, but that little stickiness that turns them on is pretty much useless so I used tape and it worked fine but if it's not perfect on the first try it seems more problematic each time it's triggered and trying to reattach it. The screen size is 13" x 8-1/4" so I had to cut it both ways and it was easy but I left one edge with a little burr so it didn't lay flat. I can't confirm it did more than reduce glare, but glare was a real issue. If you have an old laptop with a custom-sized screen, it really limits the options available.
