I bought the Podukt because I need and not the film that I did not use the protective sheath. The cover fits perfectly and the big advantage is that the shell is quite clear and thus the design of the iPad is very easy to recognize. Thus, the envelope is not a good grip and a bit slippery in the hand and gewöhnungsbedurftig. The slipperiness I see as a slight disadvantage, but for me outweighs the advantage of complete Transparency and protection of the shell. For me this is definitely a buy recommendation!
