Very satisfied. The appearance of the MP4 player is modern, it is small and almost essential in my life. It seems to me very useful because I love listening to music and it is quite frequent moments when I do not want to hear the infernal noise of the cars. This is an alternative! and the mp4 player is compatible with my computer; I put the favorite tracks and at the same time the battery is charging. Good product, good price. Thank you to you
