Input:
I own two SP90's, both bought for my kids. The MP3 playback works great, you really can't get it to skip. Battery life is terrific on MP3's because you can set it to spin the cd only when it needs to read more data. Most of the time it plays from its own memory, which uses nominal power, and the cd is still. Despite the reviews of other users here I can't complain about skipping on normal cd's either. You've got to shake it pretty hard to get it to skip.
There seems to be a lot of refurbished versions of this player for sale. Both of mine are refurbs. I couldn't be happier with the players, but if you are considering a new one, rather than a refurb, better make sure you can return it just in case.
