By cons, for one, 6 is not too much, because I have used 3 in total, the first two have contained dust between the film and the screen - -.
Now there is a little less, but I guess that's common to all protective films. To know that fingerprints are more visible against the naked screen. It really is a detail, but it forces to clean a bit more often.
Last note, I have often seen written "a pity that there is a hole that serves nothing." Well it's true, it does not serve anything, that hole in the film, is the location for the cell to make the automatic brightness control, the manufacturer of this hole to make it there is no impact on the function of the ipod.
Finally, I will say that given the price, it should not hesitate a moment. And congratulations to the supplier who issued the command extremely quickly
