To protect the scratch- and touch sensitive Touchscreen, I ordered this one on Amazon:

Thats how it looks stock. If you touch it, you often mark your fingerprints on the screen.

Recieved this one yesterday. Package containis all required tools.

Yes, it looks scratched but it isn't. First you have to clean the screen with the included "Alcohol Prep. Pad" to remove any dust and fingerprint marks. (I used some kind of Duster before) Be careful if you use the "Dust removal stickers", they really wanna stick where placed.
After cleaning you should fit that "plastic suck" on the front of your protective glass. Remove the Protective film and carefully put the glass on your screen. It is important to thoroughly clean it, also the dust on surrounding parts.

This is how it looks with protective glass. It feels much better, it's more resistant against fingerprints and scratches and it seems to be easier to clean.
