I am not sure the age range on this toy is accurate. My son is 5 years old and specifically requested this set for his graduation present (graduation from preschool, will enter kindergarten). He has several of the Hero Factory 3.0 models that have fewer pieces than the Black Phantom. I was pleasantly surprised with how much detail there is in the Black Phantom. My son followed the instructions and was able to put it together himself. It took him about 45 minutes, and then he emerged from the playroom with a big smile and the Black Phantom in his hand, which was almost twice as tall as his other Hero Factory models! The model holds up to lots of play, also. My son takes it apart and puts it back together often these past 2 weeks since he has had it, and it is still as good as day 1. The one thing I wish is that they include some extra connector pieces (little black, blue, red, tan pieces about 5-10mm long) They are small, and with repeated play, it is easy to lose them.
