Fantastic Lego to build, my 7 year old loved the lego and built it right away.
Our Grandson was very pleased with the Twin spin helicopter and built it as soon as he opened the box, he was very excited about it.
It was a gift for my nephew who is 4 years old and he loved it totally.
I got this set for a gift for my son.
My 5 year old son loves this helicopter.
Books are all in one of the packages its like all the pieces are mixed together and may be missing some.
Still work in progress as we just started last night hopefully all comes together.
