I bought this robot for my son's birthday 2 years (on site amazon was 2+) but on the box the toy 3 + ... my son was very attracted by the robot, he wanted to do to know other gift ... but unfortunately one hour after the chips were stuck in the robot can not get them out. So we will repair (we will try to send it to the manufacturer, guaranteed for 2 years, we'll see) I believe that this robot is a very educational toy, but one must watch the kids because it is not very strong. Too bad, because I thought he could play alone.
