As indicated, located in this product just a screen overlay. A bubble-free installation was not possible for me, because the rigid support film had to be completely removed before installation. The then asked goodwill application was decided negatively. Property me then the cost Displayfolie ordered by dipos. This article seven films are included, a bubble-free assembly was guaranteed at the first attempt. I'm very satisfied with this display foil for 2.99 with shipping fees of eBay. Another deduction is available for the property "mat" that I could not see in this film.
