"I bought this set for my 7-year old niece. I saved it for a day when she didn't have school. She loved it! It sat down & built every item in the instruction book. I helped her a couple of times. Overall, I was impressed with how well she followed the instructions. I deducted a star because the set should have come a storage container like the some of the other Classic sets. I guess because it's labeled a 'Supplement' it doesn't have a storage container."
