Ive had my Rio 500 for 3weeks and I love it. Save your money on buying better head phones because the ones that come with it are very clear and good. It is quick to erase the memory and almost as quick to put music on. The only thing I don't like is you have to use the battery power to put  music on the Rio 500 but its so fast with USB hookup that it dosent use  much battery power. There also built strong. I go to the Gym and I was on  the Treadmill and it fell out of my pocket hit the mat then shot off the  back and on to the floor, when I picked it up it was still going. It also  hays extra setting in the menu that is good. I think you should get one,  alittle $$$ but very good product. Also I would like to say I am pleased  with Amazon, fast delivery and super service, thanks Amazon...
