I have not yet received, but I have never had problems with Amazon so I do not think I have worries. I already have a full usb home. They are perfect: nice colors and plenty of space to store data, what more for a key? Each key will a playlist: orange for the dancehall, black for rock, yellow for trip-hop etc that my cd mp3 player will play with colors ... a good way to organize and not to lose! I recommend!
