"I have Bulit many Creator expert sets (Parisian Resturant, Fairground Mixer, Downtown Diner, and Ferris Wheel) And by Far this has to be the Greatest! let me start off by saying, I LOVE ROLLER COASTERS, with me loving legos and being a Roller Coaster Enthusiast I knew this set was for me! With a price point of almost 400 dollars I was a bit Skeptical but I can safley say the Pros outway the cons. Overall the the build is very fun, but a bit challenging at times, especially buliding the gears under the station, I had to Redo this part 3 times. besides that sometimes while buliding the collums The structure itself appeared "unstable", but at the end of the build it was decently stable. Out of all of the creator Expert sets this was the most challenging, so i would not recomend this set to anyone under 13. I love how lego took the realism of a real Roller coaster and put it into a set, I Really like the height checker, park map, no photography sign and the station itself is amazing! I love the fuction of the Coaster train running on the tracks its so smooth! The minifigures that bcame in this set are good too. For the price my only complaint is that it did not include Power Functions, but thats really minior. I TOTALY RECOMEND this set to anyone who loves Lego, Rollercoaster or Both!"
