Rezension bezieht sich auf: The LEGO Technic Idea Book: Wheeled Wonders (Taschenbuch)
big surprise - tried few constructions and could not explain why it not working for my son. He was so dissapointed of nice looking but not able to working "simple machines". In my opinion autor or some other person should review "ability to work" of those constructions...
And it is not explanantion that it is only "idea book" - when you put step by step instructions - than its no longer "only idea"
