At first I wondered if I should not order the cheaper films, but then decided to go for the atFoliX screen protector FX antireflective.
At first I was skeptical as to whether the difference would actually be so great. When the film arrived I knew: Yes, the difference is enormous!
The films are more stable than many other film that has been glued to devices. This facilitates mounting considerably. Before you just have to thoroughly clean and remove the dust possibly with tape the display. Then you can attach almost with one hand, this film even. The shape and size fit exactly and the film becomes smooth without air bubbles even on the display.
The anti-reflective effect is also very convenient. The film is slightly dull, without the image would thus adversely affected. If you have the light in the back, so the screen does not reflect so much and you do not have to dismiss the tiny viewfinder of the G12.
Conclusion: I am very pleasantly surprised and can only recommend this film.
I will in the future rather spend all of my little device a few euros more for the film, instead of sticking me with the windy, thin cheap films millimeter by millimeter forwards and backwards to achieve a nearly perfect result for ages (with about one bubble or similar at the edge).
