not resistant at all

My niece has had one that lasted barely two months, then the aircraft already working. My son also had a gift that was also short-lived. This object does not support friction, or it is a game for small inevitably they do roll. Gros resistance problem. No educational value. It's just a nice airplane. Plastic is resistant since it has not broken after a fall, but it is a shame, considering the price, that after 2 to 4 months being no longer serve only look pretty ... (I said that my son is very careful of his toys and has not abused except a fall). I do not recommend this object ...
