This mobile is also a pilot. The melodies are not repetitive (unlike others) although some dynamic, I do not put it in order to sleep. Ideal for baby entertained, he also loves watching the light base, I plan to leave him on hold later since the mobile part unclipped when the baby is bigger. In addition it is used with R6 (the most common), which is rare and they last long enough. I highly recommend it and I do not regret my purchase!
