Meanwhile, I have also tried atFoliX and dipos crystal clear premium screen protectors. Certainly in these films display image is slightly sharper but by the reflection of all light sources is often not pleasant reading. In addition, the crystal clear sheets see after using the cell phone from getting smudged. The dipos antireflective premium film makes a very good representation of the display and allows a reading without fatigue no matter what the lighting conditions, and the display makes outwardly a neat impression, hardly any traces of use. Therefore, I now use the back dipos antireflective film Premium, which I prefer clear. Attaching the Dipos films without bubbles is very good, better than all the films that I had previously. So still a strong buy recommendation!
