The film was delivered quickly and was in a very high-quality packaging. Is probably a must, because they must not be bent so :-) The guidance needs actually present day no more, but if it does, you should you the same even a loupe buy, because the writing is gold on a white background and very very small. But I was no point deduction, because I know what to do. :-) I have extensively hot shower, and then applied in the humid / dust-free room, the film in a few seconds. The alcohol cloth and microfiber cloth actually need no mention, because default is any good film here. The attachment was actually a lot easier than with conventional plastic sheets. The brilliance and feel are amazing !! This film really seems to be no film, but to be a glass. Whether and how scratch and impact resistant it really is, I now can not judge, but she makes a HAMMER impression. Why then I give only 4 stars? Because the front protector was missing. I thought that was more than strange. The packaging looked authentic, and everything seemed to be there, but that mentioned in the manual pick for prying has just been missing, such as the front sheet. Therefore, I am not sure if I have received a new product or a returns. But there were no flaws in the glass, I keep it. Total: strong buy recommendation!
