Review title: Christmas disappointment
Product review: My 9-year old daughter received the STVG-700 on Christmas, and it was initially a lot of fun. That is, until about 15 minutes into playing with it when the onscreen monitor went black in the middle of the screen and you could no longer see the lyrics. It will have to be returned for another, which I hope doesn't have reliability problems. Fun machine, but seems to have a reliability question mark hovering above it.
