My 15 month old son was immediately adopted! I was looking for games with buttons, a rotating elements, to handle short, several functions so that it does not make the turn in 3 days, and a play with melodies because he loves music and dance to the songs, and this little set (compact and space saving) combined all these qualities! Moreover, the small saw on the side that he could not use a ds first forced him to focus a little and be precise gestures ds pr happen to trigger sounds; so this is an evolving game as it continues to discover new functions; We bought it a month ago and he continues ay play every day (which is an "exploit" because as a rule he gets tired fast enough) I am delighted with this purchase and I can go about my business more easily :))
