The solid case is brill for protecting the Nano - just the ticket. And because it covers everything, the screen is also protected too - rather than have to fiddle with a screen film.
My only gripe (small) would be the cover does impair a bit the headphone socket - so some headphone jacks will not push in far enough - you may need to take the cover off to use. However, no issue with the iPod ones supplied.
Overall, very good value and colour matched exactly - I even then bought the blue set for my daughter for her to use - as too easy at this price!
