Great Product. I got this as a gift for my nephews and they love it! It took about 2 days to build. It really helps to organize everything beforehand like everyone recommends. It wasn't too hard of a build, just took time and patience. The whole process (from ordering to delivery) was very fast. The delivery guys called beforehand and were really nice. Overall I had no issues...everything came in the box and nothing was broken or missing. This product deserves more than 5 stars.
