Of all the films from different vendors I have ever tried on several iPhones, this one is by far the best. Fit as I am used to it by FoliX. Of course, it takes a little patience to position the film accurately and without bubbles. Today I needed about 20 minutes for the front and back of my 5 Series, but it is also located perfect now.
If you nevertheless discovered tiny particles of dust, just peel foil carefully again, remove dust particles with a piece of scotch tape and sheet position again. This works even prima repeatedly.
Thumbs up - i like it!
