"I bought this for my son (age 6) knowing full well that it was recommended for 16+. This is a terrific set that challenged him for a few sessions over two days. Overall i would consider this a great set, however there are a couple of minor quibbles. The ribs of the triceratops and tyrannosaurus are quite difficult to get right and move out of place easily. The posing options for the same two models are very limited, especially for the t-Rex, whose head is quite heavy for the single ball-socket connector used. None of this is to say that this isn’t a top notch set and it definitely looks brilliant when built."
