I love the idea of being able to register by reading a story and this is my voice and not that of a stranger that my son listening looking at his book. But it's a shame, it is technically not up: you have to press SUPER STRONG !!! to trigger the playback of the recording, so my son 15 months, although qu'habitué long this kind of audio books, can not trigger alone ... :( Even me, sometimes I have to resume to me several times ... So, it's a shame. After, it's still nice anyway, instead of reading it alone is the whole bed, and the fact of not having to read aloud each time is still quite relaxing. ^^ In sound, there are slight hiss but nothing too bad. In short, I do not regret my purchase at the end, but I still regret that it is not up to my expectations. :)
