This is the only protector I've tried, so I have nothing to compare it too, but I felt I did my research and this appeared to be better than most of the thin film protectors. I followed the directions in installing it on my G7. It was a clean and easy install. However; I've noticed three days after installing it, there is one corner that has worked loose and will not reapply. So far, this isn't a problem as I still have protection for the entire monitor, but I wonder how long the protector will remain functional. I think the Giottos SP8252 is the way to go as it is a glass protector with antiglare coating.
