They can apply very easily because the protective film, the first is located on the adhesive side of the actual film, on one side is about something, so that you can peel off and grab the screen protector easily.
So you can very easily handle the film.
The application to the display is then also quite simple. One has only to aim something, the iPod Nano 6th generation is not so particularly large :-), then you can see the film in principle easily slide on the display. I had not even help out, the film has been adapted directly without bubbles on the screen. A precondition for this is the previous thorough cleaning with an antistatic cloth :-)
The size of the film I find very good, there is nothing about and I can not find that it would be too small even somewhere.
For daily use, the protective film is very easy to rub off and also appears to be very robust, as it is not too thin either. The display is clear to read, without streaks, without turbidity, the film did not fall further on.
All recommended in particular, price-performance ratio. In addition, fast shipping.
