On the bottom of the cube, which has an edge length of about 8 cm, there are two small slide switch and the battery compartment.
The battery compartment is screwed childproof and can accommodate 3 x AAA cells, which are not in the package. The two slide switches allow light and sound settings.
It is only possible to activate the nightlight and this in combination with various children's songs, which are, however, played only in the form of an electronic melody, so no singing, or heart sounds or heart sounds with a Rauschton which probably calming effect on the baby or child should. Since the speakers lack resonance volume rather tinny sounds, you should keep the volume accordingly low.
The dark blue starry sky is thrown by a LED at the top of the cube and looks very appealing on a white wall, our little girl finds him anyway class. The light is not animated, it lights up and goes out after about 30 minutes.
The on-off switch, and the knurled wheel for the volume are good and solid processed, as well as the rest of the cube, so well suited for the nursery.
