“There hasn’t been many dinosaurs that are brick built, so having this one in your collection is sure to increase it dramatically. There’s good parts, and I think the set will increase in price after retirement, so get it now while it’s cheap. Overall: 90/100.”

“Overall, I love the models on offer in this set. In fact the parts selection has led to a large number of submissions in the new LEGO® Ideas Test Lab. I strongly recommend this set: the included models are great and include some new and unfamiliar techniques for Creator... More builders.”
