I was thinking that buying a more expensive protector would mean less stress for me.
I can't fault the product itself but the faffing about to install it...that is a different matter.
I've installed a lot of protectors in my time but to have 4 parts to manoeuvre to means in my opinion more chance of dust collecting on the screen before you finish the last step.
I'm glad I bought a pack of two protectors and I suggest the same for anyone.
As I said before the product itself is great but next time for me I'll just buy the regular 2 part protector..peel rub and pull away.
