I am totally technically inept and could start with the description not much of how to do that. Perhaps I would have to watch a video before. Anyway, I have 2 consumed in vain by the 3 films, in an attempt to install it ......... the foil does not stick properly after removing the protective film and the air bubbles can also be poorly prune. The film is incredibly easy to withdraw again, the problem I had from the screen protector on my smartphone, not even for my other camera that was easy to install and bonded bombproof .......
So I would not buy it again, it may also be, however, that I have made myself just too stupid. But take the view that all should be user-friendly and easy for me as easy to use people, which unfortunately was not the case.
