The screen protector is easy to stick on and in size the risk of bubbles for a layman is quite low.
Once neatly glued them not fälllt on and also the appearance and feel are not adversely affected.
The film has a few weeks on my camera behind and so far shows no matter how small scratches, which can for the time being close to a very good scratch resistance. However, should it happen that the film scratched you need for the price of 5 for 6 films not long hesitate this easy to replace.
