After I quick search in the same category, I found out that this was the perfect one to introduce my 3,5 y old son to his first real digital instrument. The layout is clear and immediately easy to learn, few but well organized buttons.The big start/stop button to execute the songs is a good design decision, and the keyboard is easily carried by him around house due to the compact size.The instruments sounds excellent as Casio always delivered, built like a tank and clear sound from speakers. What else? In sale for 77 euros a real winner
