Our son took his keyboard to 2nd birthday and immediately gewuÃYt how it works. It was equally ready, because batteries were already available. The sound is good, there are various tools and small demo songs. A manual and notes or SpielvorschlÃge Far songs lacked unfortunately entirely, although but the buttons are colorful icons that indicate that it could be something. My son has big fun with it, he can do it yourself on and off, and use Ãberall towards wear because it is very easy and no cable has. It is very robust, because it has been several SturzflÃge (WÃrfe!) Ãberlebt without scratches. What FAR me All thing is a big flaw is the fact that the keyboard very loud and the LautstÃrke not verÃndern let. So I let my baby not too long on strumming to protect his and my ears (or nerves :-)).
