Interestingly I find it then but the optional sound effects that mimic the sounds in the womb, such as heartbeat in the amniotic fluid.
The cube is placed on a plastic base, which at least visually not half looks bad.
To operate three AAA batteries are needed which are not included and must be purchased separately. The manual provides a rudimentary overview of the setting functions.
I had expected more from this device and am a bit disappointed about it. Not really bad, but not really recommended. For the price of the device can also acquire much nicer projectors as Schlummerlicht. Therefore, only two stars for this device.
