Sorry if this has been posted before but i did a quick check and nothing came up.
Brilliant little item, ALBA 4GB MP3 player with 3 different covers Black, White and pink.
Uses 1 AAA battery and lasts up to 25 hrs.
Bought one for my daughter after an unsuccessful hello kitty mp3 purchase.
You can sync it via windows media player or drag and drop files, and play them via a choice of album, titles or your playlist.
You can also change the backlit colour-choice of 5 i think.
Doesnt mention that its compatable with win 7 but its fine, all you have to do is connect it with the usb cable provided.
The earphones are also handy, necklace style which you can adjust, and a detachable thing which you can attatch to the mp3 player and then re-attach to the earphones - havent tried their quality yet tho.
Argos have also got a 2GB one on sale at £9.99.
