4GB is very good for under £20, and the sound quality's not bad. It's not of the highest quality material, but for a cheap 'n' cheerful MP3 player, it's servicable. However, although it lists the 'shuffle' feature in its description, this is not quite the shuffle option on most players. You can shuffle between songs within individual folders, but you can't (or at least I can't, and I've checked on the website and it seems to be the same) shuffle songs across all folders. So you tend to be a bit stuck with the play list. It's a shame, because it's not a bad little player, easy to use and fairly robust, and if it only had a proper randomising shuffle feature, it would have been great, but (and this depends on what you want from an MP3 player) I found this to be an irritating blindspot in an otherwise decent product.
