They only problem I ran into with this player was it was unable to play ogg format. Once in a while I would notice that a mp3 file wouldn't play or it would stall the player. I fixed this by either restarting the player or I would use the format/delete options that is built into it and just replace the file that was actin retarded. Other than that I love it. The 128 has limited storage, around 25 to 28 songs depending onthe size of the file but there are 256 and 512 models available. I bought mine at compusa and you can get the other model just make sure you call in advance, sometimes they only sell them on the internet for delivery only. Link below.
