I bought the sheets due to the numerous positive reviews and thought that you really can not go wrong with it. Unfortunately yet. The films have a poor quality, so I could not use only. The ball size is catastrophic, the cut-outs for home button, camera, etc. are much too large. In addition, the films begin immediately dust, so that a coating without blistering is not possible. I can not even explain why exactly my films so have poor quality and there are obviously so many good thereof.
