Not practical at all!
This screen protector is a lie, because the size is not the right one, I explain myself! It allows you to make screens that have no border, which is not my case, my pc is 13 inches, but with border around. This filter can only be taped with 3M, and it is very ugly!
It's not at all an attachment that can last over time. It ended up in the bin. I don't recommend it at all.
