+ Hygiene: The protectors are packed individually, protected from both sides in addition to separate slides that (1) allow the simple and lean application to the phone, and (2) The films remain free of contamination until use. + Installation: Simple, clear guidance in several steps + offering a video tutorial (in my case was not taken to complete because everything was understandable). You have to be applied at any time sheet with your fingers touch (during application). Placing on the display is extremely light, since the film is more stable than others, and is thus easily smooth draw. Bubbles are excluded. + Fit: The film sits at all ends perfectly, the recesses are also properly chosen and everything helps effortlessly attach the film, as there are no "holes", but go the cutouts to the brim. + Economic: No cumbersome extra packing for the films, the wipes and the instructions together, everything is compact packed in each individual sachet and adjusts to save space in an envelope.
All in all, there's nothing negative in my case and I'm absolutely delighted and for so little money.
