This type of film is now the 4th product trial and finally a film that is easy to handle. With the included lobules your display clean, ever good. The screen guard itself is structured in 3 layers. In the middle layer is the actual film for the display. The films above and below protect this perfectly. Only removed to 1/3 the bottom sheet to the attached small tongue it (no fumbling necessary with fingernails!). Then one adjusts the position on the smart phone and pushes with the enclosed cards (very handy) with good pressure along the sheet on the display, while pulling off the lower first protective layer. The pages with the cards from center yet well press. DONE. Last also nice and slow and shallow pull the outer protective film at one tongue kept and you have a perfect bubble free result. The first perfect result I have ever achieved. This set is highly recommended. The film itself is in daily use stable, scratch-resistant and will not peel off. With the finger operation is anyway everything is OK. Using a stylus with a soft rubber cap of resistance swipe is a bit stronger than directly on the glass, but does not interfere. The film is so thin that several stylus still work well. Helpful Highest considered concept!
