Query: Music & Moblie are worthless and do not work...

We have had two of these now. Each one had a different problem. Putting it together was not the issue it was the music box and mobile. First one, music box did not work. So we exchanged it for anohter. This time the music works but the wind-up mobile only rotates a quarter turn and stops. THe music is terrible and the so-called ocean sound is not that good. My daugter is rather dissappoinited with this after the second try. And wants to return it for a different 'type' she said.
