I purchased this so I could transfer some of my favorite cds to mp. I initially used it for the radio and it worked about as well as my 15 yr old radio for pulling stations in but the sounds was definitely better. However when I finally got around to trying to transfer cds I found out the power supply when using the cord didn't work at all. (I verified that the outlet works) I had been using the battery option for about a year (those last). I was really disappointed because I can't expect battery power to work for cds. Good thing I kept my old radio I guess, but this one sure looks better.
