The films come with a microfiber cloth and a squeegee for bubble-free application. This doctor was missing for me, but it was not so bad, because any plastic card (EC, credit card ...) is usable. The installation manual is clear and (running hot water) of the tip with the dust-free bathroom is simple but very effective. I was able to apply the films for the front and back respectively on the first try absolutely perfect dust.
The Antirefelxfolien have a matte finish - just like a dull computer screen. Personally, I am not decided because of the anti-reflective properties, but because I find the feel a lot better and more noble with matte surfaces. Also, the Z1 is no longer smeared and finally I can stop every 10 minutes to rub the phone on my shirt to remove the grease stains.
The films are very well designed with good margin 1mm, if you times a little too far to the side or easily wrong starts with the application - here match the slides to the end is still very good. Keep far perfect, the edges do not dissolve away.
A negative point however is the included microfiber cloth. That was enough for me just to one side of the Z1. I could wipe dust. After that enough dust has accumulated in the microfiber cloth that continuously which leaves on the second side. If you try it more often, it starts sometime even to be lint. I had for the second side to use your own towel to the Z1 to wipe dust. Here you should have done the microfiber cloth greater than or equal to a second mitliefern.
Overall, I'm absolutely satisfied, thank the easy application I have each 2 sheets available as a reserve. The image quality remains (but we grisselig something, just like on a matte PC monitor) very well. But the feel is now awesome and I always have a clean and classy looking phone.
