i bought this toy piano as a small portable keyed instrument for my acoustic folk band, and its great. my biggest worry was about how accurate the pitch was, and its bang on. it has a pleasing xylophone/music box sound, listen to the amile soudtrack for an example
the keys are very loose compared to pianos and keyboards, but are according to the manufacturer there delibiratley that way, and is fine once gotten used to. ive taken the lid off and had a little look inside, and it seems to be pretty solid, it has so far lasted about 3 months of band wear and tear with no issues.
so yea, great kids toy, and solid serious musical instrument if youre into that sort of sound (iam)
