"We gave this set to our 10 year old daughter who loves everything about it but particularly the chairlift feature which she finds awesome with its rope system that smoothly makes it go up and down. She also loved the fact that she could make her skier go down the slope and it would do so standing up all the way down, not falling over. Perfect descent! I rated the level of difficulty as “challenging” as it was, for her, a bit more challenging than other lego sets she owns but which, to her, made it all the more interesting! She took several hours to build it, without our help, and our children played with it a lot since."
