Most:
There we put on music as a USB key. We must order music on file for the order on the device.
2GB, enough.
The child can not access the menu (6 seconds on the two outer buttons) and set the volume for example.
There is a headphone jack in addition to the speaker.
Rather a good sound quality.
The screen displays the track title.
A very solid priori.
A timer for extinction after 15min, 30min etc.
Cons:
The device is in English or Italian ...
And preloaded songs are also in Italian ... A change prior to bidding! (Unless of course you like Italian music)
Only battery (presumably the AC power existed but had to be removed for reasons of standards)
I did stories menus, dance, lullabies etc. but it must go through the menu to change the category, my daughter can not choose, so I made a class "all ...". Less problematic with a tiny fly that does not itself.
Dixit my daughter asks me what I am now writing on the computer and only wishes me to resell the 'ternet "it is because we can make the music you want"
I wanted to put him in the evening lullaby "I will not listen to music all night anyway!", I gave up ...
