"Got this for my 6 yr old, who has no problem w putting together sets for higher age ranges like the Ninjago City and Hogwarts Castle.
He was very interested in the Hidden Side series, this being his first set in the series. Though the set looks cool and is fun, it is very weak in structure. The base of the build is unstable and is less appealing to play with because of that. My son is afraid to move it around because of how fragile it is.
I can see this being one he will not be playing w often and making the other sets in the series less appealing."
