The protector fits the Nano 7th generation perfectly. I followed the instructions, and when I peeled the backing off, it also peeled the protector off. Because it is so slim, it was hard to tell until I touched it. Of course, now it has finger prints and a bit of lint on it. I reapplied it, but it does not look as good as if I had not accidently removed the protector with the backing. Be careful when applying.
The charging portion works well, but it just has generic usb ports. There is no cable in the photo, but I did not notice this. There is no cable for charging the nano 7th generation (which does not use the same end as all other apple products).
