This Lego model is genius! First of all, Stranger Things, this needs to be great!
Lego isn't made for an upside down construction, but the designers did some clever tricks to accomplish this.
Fun feature, you have to build 2 sort of the same houses. But because there are 2 manuals (1 for normal world and 1 for upside down world) you can build this together with a friend of family member at the same time! And you will put it together at the end of the build.
Really worth the money, build time was about the 9 hours.
