"I have probably bought 6-8 sets to build with my 6YO grandson. He loves building them and playing with them. This set took under 3 hours for him to build but as soon as he picks it up, chunks of pieces break off. It was like they didn't have enough Lego's connecting the various pieces to keep them together. I tried to put it back together for him and it just broke apart even more, as I got one piece connected, another one would come apart. He liked the set and enjoyed putting it together but I am not happy that I paid $20 for a set he cannot play with."
