I purchased this MP-3 player for my daughter and am generally happy with it. A couple of things that I wish I had known: 1. You need to select between the types of input on the player before your computer will recognize that you have attached it. 2. Do not purchase an iTunes card to buy music to place on an MP-3 player. It is a fairly nice MP-3 player, just a little difficult to figure out at first.
