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!

Love secret feature

[This review was collected as part of a promotion.] This Lego set is so far one of my favorites in the Harry Potter Lego collection. It looks like a regular potion cauldron that spins. BUT it has a secret classroom inside of it. So cool! It was easy to assemble. Lego bricks were well organized and instruction is clear. I really enjoyed it. Also, the set has an extra pieces of the smallest bricks which are helpful in case you lose or break some. The Lego Professor Severus Snape is so cute. Also, I was excited about Hogwarts Logo wasn't a sticker. The only sticker in this set is a poster in the classroom. Such a great addition to my Harry Potter collection. I am obsessed

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.
