Have the facility for my son (8 years) bought and am absolutely happy with it. So far there were no problems with original CDs and burned copies (including MP3 files to run properly). Of course you can not "sound experience in perfection" expected in this price range, however, the system is completely satisfactory for a nursery stellend. Something to complain about is the remote control. The arrangement of the buttons is somewhat obscure and very chaotic. Here the manufacturer could have given a little more effort. I think the price and performance considered, 3.5 stars would be appropriate.
