Great quality

[This review was collected as part of a promotion.] Lego always delivers quality products. My daughter-in-law collects Legos, so I buy several a year. Also my kids have also started buying me the flower ones (they put them together for me) The Harry Potter legos are always fantastic!

Amazing set!

My son loved putting this together. It’s a pretty good size and the perfect addition to his Harry Potter Lego collection.

Fun to put together!

[This review was collected as part of a promotion.] This was a fun Lego to put together! Some of the pieces were a little finicky, but overall, it was a unique design. I loved that it came with a Patronus and it's a fun recreation of the potions classroom!

Prefect for any potter head

[This review was collected as part of a promotion.] So detailed! I wanted the castle but it's way too big but this is the prefect compromise. The cauldron magically opens with a stir of the stick and it opens to shapes classroom. Really fun to make come to life.

COOLEST set

[This review was collected as part of a promotion.] This set is so cool. We already have dobby on our bookshelf, so this was a perfect addition. It's SO cool the way it folds up. The instructions aren't super complicated & I love that it takes up less space since you can fold it closed.
