i bought this to play old radio shows in mp3 that don't play on alot of better machines (the encoding is low i think). they play fine but it's very annoying to fast forward one show at a time and sometimes the buttons aren't responsive at all. it stays in one spot so it isnt getting alot of movement which might increase it's life. all in all , it does the job and the sound is fine on my machine for my purpose but it certainly isn't worth any more than i paid for it. When i have the time, i'll probably test other machines to see if they will do the job better. It does give better sound than my Rio portable mp3 disk player which i play thru a headset or speakers. the Rio has very low volume (which is probably why they lost the market to IPOD and are now not making them).
