This keyboard toy I was traded (or adjusted?), Because musically very wrong. The replacement model is a little less unpleasant, though not really fair. Current technologies allow much better, even at basic prices. For a toy (for young children), ear education should be possible with impeccable agreement. I do not buy anything on the music without having been heard préalablement.Ceci being said, the cost was very moderate, and after-sales service was fast.
