Once I had to replace a protective film again, I wanted to try something new. I usually order the films for over 10 years in Hong Kong, but the shipping always takes a long time. Therefore, I decided to test this product as an alternative. So far I am very happy - I nutz the glass now almost 3 months and it looks like the first day. I can even hardly be said of really good films.
Included is also a sticker on the middle button of the Samsung Galaxy S4, because the glass is still much thicker than any film. I do not use it, as it also works well without the sticker.
