And once on (intuitive, for our daughter too!) There Whaoo guaranteed effect: the projections are superb, intense, well drawn. Not animated, but they "pulsate" slowly. The stars (and the moon) perform well throughout the room, and that, even if "Miss Turtle" is placed on the floor (so far from the ceiling). It has not placed in the bed, even if it seems safe (no spikes or anything), no need our child plays with, that's the dodo.
We have the choice [sic] one (but no more) music: it is ultimately just fine, it installs a routine part (we not need to think, and our daughter, she claims reassuring landmark ). Note that the melody is not boring for us (obviously we often hear, between naps, bedtime and sometimes at night), very relaxing. Letter to Elise electronic trombone, very little for us!
Conclusion: after the story and hugs, we lie down easily our child every night, without (too much) whims (happiness).
It is not however really suitable for the sublime nightmares projections, relaxing atmosphere to sleep, easy to carry around but it illuminates little (apart projections everywhere, the turtle remains opaque) so it's not a "light / night "itself.
Note: long battery life measured batteries, on the order of 3 weeks (daily naps and bedtime).
