Our 6 year old son who loves to play though Lego, but not tons has, has wished the set for Christmas. He alone can assemble without problems, which has made him ansich already enjoy. Since now he plays very extensively with the headquarters, which is possible, that many parts have a function (let shooting, turn disconnect, etc.) and the set not only the truck, but precisely also includes many figures and smaller vehicles. Even if he does not understand all the "ultra agents" background, a great and complete toy.
