Query: Worst CD Player I ever had

Can not agree more with the previous reviwer. My player got malfunction in less than one year. Worse, it swallowed my five CDs. I don't know how to get them out:-(. This product boasts its elf having excellent sound quality. I don't think sound query is important here if it can not even play CDs.
