I already had several screen protectors, this is by far the best! Usually you can stick a film only once, this is glued incorrectly and pulling them off again, we see again and damage to the foil. Not so with this, they can be repeatedly removed again and refit, it looks like new and is liable. The size of a millimeter Also is probably accurate to the "hundredth". Because of a film for a device for which the company I had offered no film contact, this was extremely friendly, they made this film as desired.
