The toy does not work, after 15 days of use !!! Normal use yet not drop or shock .. I am very disappointed, especially for my son, who received this toy for Christmas and could use a few days ... I'm angry at not finding after-sales service or repair service, while it seems clear that this toy has a big flaw reliability !!! I had read a similar comment before my purchase, and I had thought of an exceptional case, but no! This toy is defective ...
