When bring him it started already, needed 3 films (attempts) until I with a befriedigendend result on the screen had. Beautiful would have been here if you could have a tab to the protective film "sticking" to the side to remove cross, so that I can apply the film transversely. Often had the problem namely the super top sat the film, but was crooked down and therefore not rested properly. What I experienced as unpleasant was that while such by the manufacturer, I encouraged the film with a debit card (in order to smooth out / air bubbles strikeouts) muster, I had brought me some scratches in the film. I must say this is the first film which already gets scratches when acquaintance with a debit card, but all the others were also quite something "solid" or the material thicker ago. But now we have to get on it, because it became a next problem. If you stand in the sun outside or uses his phone in good lighting, the film begins to reflect. The display of the note itself so little mirror, but with foil wars but very uncomfortable. This also includes fingerprints (well, just "touch") are partially visible, even when using the screen with a light background. All in all, I am satisfied not with the film of Mumbi and look around for an alternative.
