Offered to my four year old son, please also much to his brother seven. Very easy to create vehicles by model or imagination, but also furniture, characters ... And then up stories! I admit that I like to play with me too! The storage barrel is convenient, a little smaller to manual (although it fits into the barrel, not easy to put it after the parts). Only small problem at the end of one week the setting of one of the wheels is broken, I would have liked more robustness.
