The package contains three guards front and rear, allowing to "miss" during installation (or replaced frequently).
We finally saperçoit three protections, it will not be too: they are a magnet for fat (this is where we see that we really hands full). Even more annoying, protecting brand easily. I'm more of a cautious nature, especially when my equipment is recent but within days, films were scratched (not to put the laptop into my pockets as I'm used to, with the keys and everything shebang ..)
In short, if your goal is to protect your screen (by causing scratches mark protection, even change them regularly), and if you are not allergic to a daily cleaning of the surface, this is still recommended. By cons, if you want to avoid (as much as possible) the appearance of stripes, go your way
