We had to purchase this RCA Pearl for our daughter because her MuVo player was stolen. Okay we did not have to, but we so enjoyed the peace we had when she had her other unit we were compelled to do it. The store was out of the MuVos so we opted for the RCA as the price and features were almost the same.
The RCA Pearl has turned out to be our daughter's favorite, over the two, because it is more compact, measuring in at a little over 3"x1"x 1/2", and came preloaded with some songs she did not own and some learning audio textbooks. The texts I liked because they cover history and science--not her best subjects.
This unit was rather complicated when it came to loading the software to download music to it. The instructions were vague as to which program you should put onto your computer. Once you got there, though, the software became more valuable to me than the mp3 player itself.
The software is Yahoo Jukebox. I had problems with disc copying/recording software that I had purchased for our computer a while back. I had to leave different things on our hard drive that consumed valuable space. I was able to use the jukebox to put the material on a disc and free up space on my computer--a God send.
The RCA Pearl has ample storage for 300 plus songs, has a shuffle feature, shows the names of the songs along with the artist, and can record outside messages--as the other unit did. One thing it lacks it the lyric capacity, but that takes up space anyway. The LCD screen has background color choices which is nice. The best feature it has: a micro SD slot for additional memory!
I think this was a wise replacement choice for our purposes considering the teen likes it. The extra memory slot makes it even better. (Some research I have done puts those SD cards at around $20 on average)
