Unusable for iPhone 5 / 5s

Have all ordered films, a total of 4 pieces, consumed. All films still had air in several places on the edge of the film, because the film did not fit as desired. The air under the film also lies not removed by a card or otherwise. Never had such problems deposit a film. The quality is probably reasonable for the price. Have now but resorted to expensive brand directly from the Apple Store and everything was perfect, never-Mumbi screen protectors. Save here not worth while, at least that's my experience.
