I just received the two Klastor MP3s (blue and pink) that I purchased for my daughters for our holiday, hopefully to keep them quiet for a while on the plane!
I was pleasantly surprised by these, they look cute, a decent size and come with earphoned and USB cable in a little clear plastic box.
The instruction manual is complete gibberish though so be prepared to just fiddle for a while until you find out how to work it. Despite some of the reviews I couldn't figure out how to just 'drag and drop' music files so I ripped my CDs onto Windows Media Player first, then dragged the files over to the MP3. It seems to have worked fine.
4GB is an enormous amount of memory for the price, you can upgrade it with a memory card if you want to but 4GB is fine for my daughters needs.
These make great first MP3 players for children as they are decent quality but its not a disaster if it gets lost or broken etc.
I've not explored the other functions yet (games etc) but mainly I wanted these for music anyway.
I've not fully charged them yet so I can't comment on battery life, but if they last a couple of hours I'll be happy.
The earphones aren't the greatest (not too comfortable and not the 'in-ear' type which I prefer) so I've bought seperate earphones.
Summary - excellent MP3 player for the price, good entry level player for children or as a cheap everyday travel one.
