I've had skin it skins for several of my phones (yeah, I'm hard on cell phones. And shoes. And I tend at thirty four to have a lot of bumps, bruises, and scrapes. Call me Grace), and I have been pleased with them.
In fact, I have had to remove the skin from my ipod on a number of occasions, and it actually came off and reapplied better than the decal girl skin I moved from one kindle to another. Now, it could just be that the nano skin is much smaller and two large pieces, and thus less likely to stretch. But I would recommend them. Seems like I have a Jimmy Buffett/Caribbean Soul skin on my blackberry...yes I do. I wouldn't worry about the quality. The template, maybe, but not the quality. Enjoy!
