I have GGS "stick on" protectors on my D7000 and Nikon V1. I want to buy one for my D800, but I now see two types, the stick on one and one similar to the Nikon screen protector except of course clearer. This is the GGS III. Has anyone the latter protector and if so what would you see as an advantage over the Standard GGS please. A link below to the one I mean.
