First, the really good packaging should be noted: Each of the four sets (one sheet for the front and back) is packaged separately, also included with each set a small cloth made of microfiber in which does a good job at the mandatory pre-necessary of smartphones. By right "dose" adhesion of the protective film on the support film, the protective film can be completely controlled and apply without bubbles. The films are made-to 100%. The feel is comfortable. By easily roughened surface fingerprints are hardly accepted. The reflection on the surface is minimal. In the product description on Amazon should be clearly pointed out that it is composed is set from the front and back. This simplifies the purchase decision also.
