Brought this for my 8-year old stepson as a father son project to bond together. One BIG recommendation and first thing to do, there's a QR code on the manual to scan and download an app for iOS or Android to simplify the process with detailed step by step picture illustration to put it together.
Lego(s) come in 3 bags to make connected main pieces as a whole which simplified the process which I found easy to absorb and locate the right legos per instruction manual. It was fairly easy to put together and had maybe two errors where a single piece was assembled in reversed. Highly recommend and makes a great gift!
