If you are looking at this item you probably own that great little mp3 player, the Sansa Clip+. Unfortunately that means you have very little choice if you want a case for it. If you owned an I-p*d then you could pick up a case made of exactly the same material and of equal quality to this for a pound from any pound shop (some even have them at 3 for a pound) but because the Sansa is far less common you have to pay a premium.
The case is thin, unnattractive rubber and very expensive for what it is, but there aren't a lot of alternatives. My case also went a sort of grey colour very quickly and looks far worse than the Sansa does uncovered, but as far as doing what it is intended to, the only problem is the lack of protection for the screen.
