Disadvantage: There is only 1 sheet and should they get damaged, you have to buy a film itself again.
For the price 2 sheets would be more equitable.
Otherwise, a film, which needs no additional material such as adhesive. Can be good and easy to apply on the screen and when you remove the foil no adhesive residues remain on display stick.
This film is for all touch devices a round and clean affair.
Highly recommended!
