I really wanted a cover that is not stuck with glue, but can be removed without residue. And in my experience, are films like this more stable and better apply without bubbles. Small bubbles there are in applying, but which disappear after one day. The film draws on by itself and can be relatively easily and smoothly apply. A doctor can help anyway. There are two protectors in mind that are marked with an adhesive. The bottom sheet must be removed to expose the "sticky side". Then you should remove with a squeegee the bubbles before subtracting the upper film because the doctor may scratch the sheet. Unfortunately, I had to throw away the first film that I've taken with your finger on it, what to do in any case. And unfortunately, the film is not completely fit. There are millimeters, but because the film not bonded really important here, because the corners then float in the air. I have not succeeded, despite repeated pulling off that to get corners flush. I had to cut it off with a pair of nail scissors. That could certainly be improved. You also have to really pay it, no lint or crumbs before applying to have it, which can be seen in any case. And make sure that the cutout for the camera on the right side. The film itself is applied almost invisible. I notice no loss of image quality or the like. Pay attention not just on the edges and the camera cutout know you do not mean that a film is on it. They can also be cleaned well and remove without leaving residue. For these reasons, only three stars, but still okay and in my opinion much better than adhesive films.
