Good and inexpensive protective film!

I bought this protector and had the following expectations:
- Optimal protection against scratches and damage to the display
- Good adjustment on display
- No reduction in image quality
- Inexpensive

First ertsmal the price: Compared to the films which can be found in the large Electro-markets, this offer is really a bargain and worth it as a film lasts long and 5 pieces are included per pack. So here's a +.

Protection from scratches and other threats on the screen I can also report as positive. So far the film has very well protected. So here also a +.

The film fits relatively well on the display and has all the right places, the omission for the home button and the speaker. Air bubbles and other disruptive factors I could handle by the operating instructions. So here also a +.

Furthermore, there is no change in picture quality - that is, the colors remain good, it's all to see but from the touch (for example when over wipe the home screens) it is a little more resistant. But you get used to. Therefore, a +.

So all of my expectations were met with this film. A very clear "+" and a very clear recommendation!
The only reason for a "-" would be the heavy attachment or mounting. I did not get it the first time. However, I've noticed that many (even the iPhone etc.) had their problems with the application of protective films. Therefore, 5 stars !!!
