My "old" protector has a full year served its purpose and that very well. On my screen are no scratches, even though I already stow the key and the cell phone in a pocket. The Mumbi I bought price and features. Delivered 8 films, a very good description, a little microfiber cloth and a plastic card to apply. Perfect! At this price, and the idea that you have 8 pieces available, you can versemmeln the first slide when applying quiet. Practice creates masters! Since the film can not help it :-).
How well the scratch protection works remains to be seen. I am optimistic because the film makes a very strong impression. The functions of the cell phone's not stand! Everything can be just as good and easy to operate, as no film!
Excellent! I would buy again and recommend it therefore!
