Foil can be attached easily and is quite thick. This also does not dissolve as quickly again. my holds already several months without problems. However, I must also say that a small production error. The film was cut out at the central key. On the left and right keys are not. The result is that the film in each case around the keys does not rest properly. Operability is given anyway, at best, an optical flaw.

Just called me the seller the film. He had read my review and gave me the tip to remove the film to check whether there is still the film was placed on the sale is attached to the two keys. In this idea I would never come alone, now the film is on perfect, were indeed enough films about to solve this problem. A big thank you to the seller!
