Only at the 3rd attempt (which I made before 1/2 hrs. - So do not know how long the hold) keep the films to some extent. The first 2 dissolved within a few minutes from the edge, both the front and the rear. Instructions are none available (in other films is about a step-by-step instructions here and an adhesive to remove stubborn dust, and a small map to find out the bubbles). The only auxiliary means is a cloth to clean the surface. 3. As soon as the film also falls away (I would be surprised who you long holds) (had z. B. ScreenSkin which as a good experience for me. On my iPad mini), I'll try a different brand.
