May be a good game for kids, but I definitely not recommending this game to anyone who are getting this as a karaoke solution. This game is more like a sing along than a real karaoke game/system; on top of that the songs collection are limited.
The scoring system and the pitch identification are basically BS. Basically, you will still get some scores and possible correct pitch as long as there are noise going through your microphone (yes, even though you are just talking or humming or just totally out of tune).
As mentioned earlier, this is a sing along. What I am trying to say is that, basically you are just going to sing along with the artist of your selected song choice. They are not muted for you to sing.
Does this worth even $5? I would have to say no. Is possible that you will feel more enjoyable singing along the radio or your mp3 players than this.
