Even if you don't have any children, you can still appreciate the I Can Play Guitar from Mattel. I suppose that this is intended to be like Guitar Hero, and there is an interactive video game that is a lot like it.

With three C batteries, you can start to shred right away with strings, fingertip chords, and even a whammy bar. In addition to the "Guitar" mode, you can hook the Guitar Wizard program to your TV and play the games it comes with.

Unfortunately, in the TV mode, when you play the guitar, you don't hear it on the guitar. However, you don't really have to, as the I Can Play Guitar is designed to teach you how to play. I also found that the strings took a lot of effort to strum, so you're doing to get a lot of finger exercise.

All in all, I see the I Can Play Guitar as a good teaching tool for $99.99.
