My son had to have one of these. So I bought one even though it is WAY over priced. It takes 5 minutes to put the nano in it and takes way to too much force to put this on. The clip on the back stratches your ipod and yes, the rubber does prevent your nano from sliding around the table top or dash board it but is now impossible to slide into your pocket. Also the screen "protector" is a joke and slides around and ironically scratches the screen. It too is almost impossible to install.
