I had come to despair of finding a music player for my children (twin 2 1/2 years) who nevertheless love it. With the ocarina, everything is adapted: Strength: They have 3 months now and despite numerous falls 2 always work very well. Support MP3 so that no cd scratch, lose etc ... It connects to the computer and its files transfered by creating the folders you want. The child has access to only one folder at a time selected from the parent menu) Simple for children: 3 buttons (front, rear, pause / play) Simple for parents: the simultaneous pressing of both arrow gives access to the parent menu: Settings of volume and folder to which the child to access (allows a folder "calm rhymes" for example if we want her child to sleep with). It connects via USB to the PC and is recognized as an external hard drive (no need to go through a platform like VTech toys for example) Small so easily taken anywhere.
It is true a bit pricey, but the quality is well worth the money. (And its life also, in my cd player child at 30 euros did not last one month, let alone cd ...) My son no longer loose. In short you will understand, I am delighted and I recommend it widely.
Small update on 01.09.2014: Just over two years after my purchase and so my first comment: ocarinas my children always work perfectly!
