I bought a 4GB one of these for my 6 year old daughter and, at first, I thought it would be too dificult for her to understand, so I didn't give her the instructions, which were poor. Fiften minutes after opening it on Christmas morning, she had worked out how to use it herself with no assistance. Because she had no instructions, she just started exploring the menus herself and had managed to load music on and play it much to my amusement. After a bit of coaching from me, we had converted her CD collection to MP3 format and loaded it on to the player for her (it has to be converted to MP3 format first - we downloaded a program from the internet called FREERIP which was a dawdle to use).
Her best friend got an Apple iPod which is three or four times the price of this item and, as it was only meant to be a stocking filler, I couldn't justify spending so much. However, they can't tell them apart and she hasn't put it down since Christmas - no other gift has captured her imagination for so long. She has discovered music in a big way now. The sound quality for such a cheap item is breathtaking.
I would give it 5 stars for quality, 5 stars for ease of use and 5 stars for value (more if I could), however, the instructions are basic at best.
So I bought myself the 8GB version which works perfectly in the ipod dock in my stereo system meaning I can play about 1800 tracks in the comfort of my sitting room without having to use earphones. The sound reproduction is impressive.
