The protective glass was very well packaged with me. The assembly instructions are extremely easy to understand. Before you should practice a couple of times dry hangs the glass permanently, so the proper placement no longer difficult. Then just remove the protective film and place glass. The rest goes almost without saying. The bubbles drag itself out independently and is fully supported on the glass. The glass contributes to very little and does not interfere. The screen quality is not affected. Can only recommend, price-performance are perfect glass.
