For now she can not really use this toy in autonomy. The balls placed in the right ear of the elephant stand by the wrong, but those placed (or fall in both the trunk outputs) in the left ear make a small circuit (through-the yellow curve) and arrive in the belly of the elephant. My daughter is still not enough to take the unglazed shot in the stomach and hand in the left ear. But it allows us to play both
The disadvantage of this toy is mostly unable to cut the music, or at least to decrease the volume. blower means a little but is less intrusive than the music itself (a brass band in the long run it's annoying). Finally, we must clarify that it is quite bulky.
Despite its flaws as a mom, I love this toy, and above all, the main tester, my daughter seems to have adopted!
I therefore recommend this toy unless the parents are really sensitive to noise.
