Perfect application on the screen, but it was incredibly difficult for me to get rid of all the air bubbles. Eventually, I managed to do it. It doesn't affect the image quality at all, in fact, it has much better clarity, I would say perfect, than 20 euro glasses. Of course, it broke in the exact same way as the more expensive one I had, although it didn't shatter like the expensive glass. At least, though, this one costs 6 euros and not 20, and it is also better in terms of clarity. I will buy it again.
