"My 9 year old loves building legos and was excited to build a set this big. All the bags are labeled which makes it easy to follow along with the building instructions. The instructions are easy to follow as well and have pictures showing how it should look. With this set being a much bigger one compared to others my son has built it is very time consuming. It definitely will keep you occupied for sometime. It took about a week for my son to actually finish it and he was super excited when he was finally done."
