Plastic saucer and quite heavy metal robot, so good robustness.
Attention to the head of the robot which is plastic and rotates 360 °. It is easy to break.
If you leave it to a child, we must explain the steps to remove the pieces (fulgurates to point hastéro ax, etc.) and set / remove the saucer.
Mine has 5 1/2 years and I explained it to keep it always with both hands, without sudden move ...
He is so happy with this toy he told me he would never be another toy!
However, I had to pay 37 euro to the Post for customs fees (I ordered it on Amazon from a dealer in Japan) in addition to the postage, not to mention the time (3 weeks).
Thank you the French customs. It is a solution to bail out of the state.
