The set this is based on, LEGO 21137 which retailed for $250. You will not get a 1:1 of that set. It's the same size, but it doesn't come w/ the light brick gimmick that lights up certain parts of the mountain. There's also missing details within the cave, or the mountain house doesn't have the furniture, etc. I've bought replicas in the past, and they've always been almost 1:1. I got this set for $73, so for a third of the price, I can't really complain. It's just that sites that sell this set will use stock photos of the original LEGO set which is a bit misleading. However, this is what you will get w/ this set. This set is massive, and it'll still have the presence that my 8yo will love. It's large, its fun. For the value, yes its worth it. For an 8yo, it's definitely good enough. The instructions are compressed and not easy to follow, but an adult who's use to knockoff Legos its good enough. Don't expect your child to build this set. So I'd say its 90% of the original set for a third of the price.

My boy was really happy with the set

Everything was Perfect, thank you!!

building this is as difficult as trying to learn how to use a manual car all by yourself while having a stroke

Very good :)
