Film came quickly by mail and had accompanied all it takes. Have cleaned the screen, yet quickly tapped the Dustremover via the display and secured the Justierstreifen on the slide with the accompanying towels (alcohol and microfiber). When I hatt then properly positioned, slowly released and removed with the cloth, the air bubbles. Then, the film laaangsam drained. She has 'drawn' by itself and without bubbles on the screen. Finished! Fits perfectly, is not binding, and nothing restricts the display is protected. Whether the film can withstand hammer blows, we have obviously not tried. But otherwise stated no restrictions in the usability of the tablet. Caution: You should not press as the mobile phone with a card or scraper this film. Carefully position and drain. That was :-)
