It's a toy. You can hardly consider it much more than that. However, it is conveniently small and battery-powered and travels easily. If you see one at a garage sale, get it, play with it for a few hours, and give it to the neighbor's kid.
Comments About the Sounds:
A cheesy toy keyboard that you could probably pick up at a garage sale. It has an amazing 99 patches, and most of them sound different, which is a bit of a surprise. It has a handful of cheesy rhythms like most toy keyboards.
