We purchased this for my son's 8th Birthday. He loves the Lego Movie 2 and has been talking for a while about getting a Rex Rexplorer set. He was so excited to get this one (although he had hoped for the larger set). It took him about 4 hours to put it together. He loved putting it together but it just sits on the shelf now. Seems kind of pricey for a 4 hour build.
