Our son was dreaming of an airplane to play with - and we got this for his birthday. The idea behind - is fantastic, the daddy figure with a baby and milk bottle, the airport, the open and close functions, the staircase and car that one can be put in...But it’s just absolutely unstable for playing. Basically we have been rebuilding this airplane about 3-5 times a day, I don’t even use instruction set anymore as we know it by heart. The second you try to lift this airplane up and move it from one place to another ( not even attempt to play “flying” with it) it crumbles like sand in the hands. The construction is just not stable enough. It’s been even unstable as you build it up and notice how weak/shaky all connections are. And the heavy “propellers” and engines - there is no way they can keep hanging one thin tile - those we don’t even try to keep hanging. It’s such a pity, we have an entire collection from Lego 30 years ago - grandparents kept all whole and intact, and even our smallest one - 2,5 year old can play with those amazing fire engines with lights and sounds (30 years old!!!) and they never fall apart. From my opinion it’s just faulty design for the functionality of this airplane.
