Got this for my 4-year-old nephew and he built the whole thing himself in about ten minutes, which never happens. The Ultron figure is chunky enough for little hands to hold onto, and the two of them have been "fighting" on the kitchen table all week.

My 4 year old built the whole Ultron figure by himself, which never happens with his other sets. The pieces are chunky enough that he doesn't get frustrated, and Iron Man's little blaster actually stays on when he swooshes it around.

Bought this for my nephew who's just getting into the superhero stuff and the big chunky pieces were perfect for his small hands. He needed a bit of help snapping Ultron's arms on, but once it was built he wouldn't put it down.
