2. Back and front are well protected. Have now some scratches on the film, but they are never penetrated to the actual equipment enclosure.
3. The choice between back with cut apple and the tripartite ensure even on the back for unobtrusive protection.
4. But what has moved me after about 2 months to the Top to Bottom to "deprotect" was the fact that the small films stuck out on the glass parts (antenna cover) sometime at the edges. During large parts held perfectly in the aluminum part, evident since then but the disadvantage of a 3-piece back sheet: There are simply very many starting points for Kantenumknicken.
Overall, however - if carefully applied - good mumbi Quality. Good grip and very inconspicuous. For the price still a recommendation.
