Where to start I have had this for 10 years and it is still ticking that alone is a tesament to how well the thing works. Over that ten years It has traveled with me to over a third of the world. This is to include half a tour in Iraq. It has been dropped and has been trough airport security more times than most people. Because of this I have never had a reason to buy an Ipod. And to be honest for music I would rather use this. Only reason that I own anything like an Ipod is that its my Iphone. So I think that the Xtra is by far the one of the best mp3 player made.
Positive

Felt great until it dug into my waist while sitting causing damage to my surgical site. Now I'm in pain with and without it on.
Negative

Book shipped quickly and was in excellent condition as stated. Easy transaction would buy again
Positive
