The atFoliX are just super! They are tailored for my phone display and also for the back. I find the set with the foils for the back very useful as the Z1 Compact the back of a sheet of glass, like the Z1, but a plastic glass is not scratched easily and this. I could muster the protectors without bubbles and the grid on the carrier film is very helpful to the slides to mount straight. The manual is also very good! They are super clear, and I hardly notice - the picture quality is not deteriorated. The touch screen we also hardly or not beeinschränkt. The only shortcoming is that only a cleaning cloth with three pairs film is. Otherwise TOP screen protectors with justifiable price!
