This set was purchased for my son as a gift. Everyone knows his absolute love of Legos and Ninja Turtle items. Let me start by saying that the age limit on this doesn't mean a thing. I've worked with my son on how to put Lego items together, and how to read the directions on his own. He is 5. He absolutely LOVES building Lego items. This one was among one of the easier ones that he has built, and he did it with minimal help from Mommy and Daddy. All pieces were included, and the directions were not confusing for him at all. Once they are built, he plays with them for a while as is. He enjoys making the turtles fight the "bad guys". It has since been disassembled, but will be reassembled once I go through his big bin of Legos and gather the pieces that he will need.
