not suitable for musicians, not recommended for children

The delivered me instrument plays on the white keys in C sharp major. Transposition is not possible, therefore not suitable for interaction with other instruments.
The buttons are very tight suspension. For single tones that goes missing when chords easily, even with me as a practiced musician, a sound.
The sounds are for musicians ears painfully bad. The children should also not do if they are to develop an interest in music.
The auto accompaniment droning incessantly chord garlands that makes each tune playing to accompany pointless.
The plastic case is deceptive two great speakers in front, something like basses come there but not out.
In summary: A pure toy, which is perhaps the short term interest of children.
But who wants to generate interest and fascination with music, could hereby have the opposite effect.
However one should really spend money.
