The shipping was very fast, within two days after the order came the packet to me. The protective film is wrapped a sheet protector with English operating instructions. There are no instructions for attaching and any German instructions. But that explains almost without saying. It draws from the thicker carrier sheet and sets the milky keyboard protector with easy sticky underside on the keyboard and press it firmly. They can be at the right place and easily removed again without residue. I am writing this review so as my first attempt and it works very well. The film stays firmly in place and does not slip. The film feels like a latex glove on, so pleasant on the skin. It actually reduces the noise while typing (which continues to work very well) and includes all of the keys of the great keyboard (incl. Number field) thoroughly. I can recommend this film very far. The white residue which mentioned another customer, I can and hopefully never notice. To protect the keyboard from abrasion through tap and dirt of all kinds, I will use this protector certainly long.
