We decided to take complement this mobile, less aesthetic but effective with baby.
This triggers alone hearing the baby voice, projection and music last 18minutes, it has a small remote control with 3 preset modes, one is not forced to use the arm with the characters (snaps and unclipped very easily), the pilot (moon-shaped) lights up gradually.
The -:
The hum of the disk of the projection is unpleasant even if it is not very strong.
The volume control: position 1 even the sound is strong, it would have been better to turn a knob. But by putting a film on the speaker gives a reduced volume and comfortable to cradle baby.
