Did these films ordered 2x and until the 4th film I managed to install it well with minimal amounts of bubbles at the bottom. But even if it is well mounted mirrors this film without end and fingerprints can be seen on it without end (More than without film!). For this reason, it is absolutely not recommended. Property me then the "PIXXENO A80MK Screen Protector Samsung Galaxy Ace S5830 / S-5830 - Premium quality (anti-reflective, hard-coated, bubble-free installation)" ordered and is simply highly recommended. So get rather expensive film as rumzuärgern you later with cheap sheets. For the price, the film is certainly OK, but for me it was a waste of money.
