I bought this for my 9 year old daughter at Christmas. She loves to sing and has a talent for music. She was so excited and played with this for hours each day. We have not had any trouble with the Karaoke machine and found that it was very easy to operate. It also came with 4 CD's that hold many common tunes- ("kid songs" and some "oldies" too). We bought her a High School Musical Karaoke CD (instrumental and vocal) to go with it. She absolutely loves it and we are glad that we bought an additional microphone so that her brother can also sing along too. There is also a dial that makes the kids' voice "echo". They love this feature and have lots of fun with it too. Make sure that you buy CD's that say CD+G so that the words will be provided on screen with the music. I think that it what you have to look for on the CD case. It will not provide the words on screen if you use a regular CD. We definitely recommend this product. It is just what we were looking for.
