Guys, don't know if you have seen one of these before but I just got one and they are pretty cool :)
Just thought this was an ingenious device as all the other ones only allow you to play a USB MP3 player, not a pen drive.
It has all the controls on it, I don't know if it will play directories, but I doubt it, I just whacked 30 songs on mine and it worked fine.
I paid 16 quid + postage from USA
