Cute at first glance, but quickly insuppportable

My big regret Christmas, I bought one for each of my girls, it was their first choice, way ahead. They are very noisy, what they say in French is quite limited, even after hours to support their babbling is furbish. They went through all the moods (5 in total), and the evolution is not obvious. The app does not work on Android in terms of translation ... In short, I am disappointed, and they also. After just three weeks, they get really involved and stressing almost to the idea that they wake up.
IT must specify (that was not planned) that you can not turn it down. There is no button "off"
So aside from the nice face and sweetness, not much positive.
