I have since the film today. You could easily be on the phone "stick" where they do not really stuck, but holds by antistatic. I think it's great to protect the screen of my Samsung S8000 in this way, because I'm not a fan of mobile phone cases (Why? Because I do not want to get out there every fumble my phone when I need it and for reasons of space).
Unlike other vendors, this film is quite favorable. Disadvantages I could not discover! The instructions that came, incidentally, was helpful and good!
