The cube projected a night sky on the ceiling, which is quite ok, but is offset in addition to stars and moon with projected points. Well, why is that? But baby it is not noticeable. The music is loud plärrig in setting, in quiet setting just fine, although I must say there that you could make the musical side much better. Very irritating I find that the whole thing just three minutes to the end, and that you have to restart the device again when baby / toddler longer to benefit from it.
The period is too short, and it creates an uneasiness when parents or caregiver runs every three minutes in the nursery, for the restart.
I unfortunately do not really recommend the Nachtlich, sorry folks.
