It's fine. I was very confused when the instructions jumped from page 33 to page 44.

Verified Purchase:Yes
I remember buying the original Harry Potter potions classroom set when I was a kid in 2001. Building this updated set brought back so many fun memories.

Got 2 of the same portraits
on October 22, 2025
Posted by: Brown Eyed Girl
This is a cute set with good minifigures but I was super disappointed to get two of the exact same collectible portraits in this set. I know it is random but the odds of getting two of the same when there are 16 of them seems crazy. The set looks a little weird with 2 of the same portraits on the wall but it also looks weird leaving it blank. Would have been nice if Lego found a way to avoid this issue.

Response from LEGOBy Alina, LEGO® Customer Service, October 23, 2025
Thank you for your feedback! We're glad you like the set and the minifigures. We understand your disappointment with receiving two of the same collectible portraits. There are 16 different LEGO® wizard cards to collect, and since they’re packed randomly, duplicates can sometimes happen. We appreciate your understanding and will pass this feedback along to our team for future consideration. If you need any further assistance, feel free to reach out!

Very condensed yet expandable

The designers did a great job with this set. I'm not a huge harry potter fan. I've probably bought 2 or 3 sets ever (including this). The price is so-so depending on what you value. Normally I'd say this set is about 5$ overpriced, however the build quality is stellar. Pieces being able to be popped out to place where ever you want is a great foresight (lecterns, ingredient bowls, desks).
The stickered pieces do look great, however I always struggle with smaller stickers. I would recommend any families having a parent apply the stickers for the curved tiles and the glass ingredient bowls.
Keep in mind this set also has loose elements (In the bowls). I enjoy them from time to time so it's not a big deal.
Overall: while I have no intention of buying any larger Harry Potter sets, I'm thoroughly happy with this one. If you're trying to save money where possible, I think it would be very easy to find this eventually with 4-5$ off.
Never made a review, just wanted to give massive props to the designer, and Lego financial guys not price gouging this beauty.
I would recommend this to a friend!

[This review was collected as part of a promotion.] It was a fun solid build. I'm a big fan of Harry Potter so it was fun seeing the miniature potions.
Really hoping they continue to expand this series

Favorite HP classroom Lego
on April 7, 2025
Posted by: MosquitoLindo009
Love how you can rearrange most of the pieces, great as a playing feature and to make small sets feel bigger
My fav set from this new wave, classroom location are always fun but this one is specifically amazing with all the potions and potion ingredients (extra points for the new pieces really cool stuff)
Great minifigure selection!
Just great design and thinking all around in every product of the wave so far truly incredible 👏
