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

Retailer reviews
Summarized retailer review data when available.
It's fine. I was very confused when the instructions jumped from page 33 to page 44.
Really enjoyed building this set as I like the new sets that are enclosed. Love the small potion detailing. Good price too for the amount of pieces. Passed a few hours to complete the build.
This set is amazing it looks so good In the hogwarts castle so fun to build 10/10
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
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 👏
These little foldable play sets are a kind of upgrade to the previous Harry Potter moments sets (the foldable book sets) I love them all for their own uniqueness but it’s nice to see that these ones can be connected and incorporated into the new Hogwarts castle modular sections and even when folded everything can still be kept in place to look around. This one is based on those early scenes of Snapes potion classes and the detail is great and I love all of the little potions and bottles and the sticker details are reasonably accurate too. This set has three minifigures, we’ve seen Seamus a few times like this with his signature blown up face, we have Hermione and a new one.. Pansy Parkinson from Slytherin house. This early version of Pansy can actually be seen a lot in the first few films aside Draco and his crew -she is not a major character but it’s nice to include this minifigure due to the fact that she was always there. I do love all the Harry Potter sets and I think they keep getting better all the time and I’m so glad they keep making fresh ideas out of these movies and even after 20 or so years from the early first film like this set. I even love the way the packaging is kept all the same and familiar too. I hope they continue to keep up the fresh ideas without repeating too much but so far I’m really happy. The only little issues I found in his set (not that this really matter) is underneath there is a space left for a 1x1 grey square (see my photos no.3&4) but there is a spare luckily so you can just pop that in if it bothers you. Also I think the potions ingredients jars need lids though these can be bought for 10p each from Pick a Brick online (piece number 6163901) But considering there are brick budgets for sets I think they made the best out of the piece count as possible and is definitely worth the money. I love this as a stand alone set to look around and also I’m looking forward to seeing more of these and seeing how they all connect. Thank you.
It was a fun solid build. I’m a big fan of Harry Potter so it was fun seeing the miniature potions.
We were so excited to get the LEGO Hogwarts potion class! The box is very eye catching and colorful. Each bag is labeled to go with the instruction book that is very detailed and laid out in an easy to learn to build format. Very durable and long lasting once assembled. Amazing addition to any Wizarding world fan!
Love this ! Assembly wasn’t too hard but still challenging having different parts. Legos are always incredibly entertaining but who doesn’t love legos !!
This was an amazing product. Everything was labeled well and packaged neatly. Me and my wife love putting this together. We are both fan of the Harry Potter books and movies.
Very easy to put together! The details on all of the pieces are amazing! Can easily be folded for better storage or put all the way out for easier viewing! It was very entertaining being able to put the pieces together!
My daughter absolutely loved this set. It was super easy to put together and she loves Harry Potter. Took her about 2hrs to complete and it’s going to look great on her shelf.
Absolutely love this Lego set! Super detailed Hogwarts potions room, great addition to the other sets. Challenging enough to keep you entertained and easy enough for even young collectors.
my son enjoyed the new details with the potions in this set.it was also cool to have pansy and Seamus in this new set for change.perfect build quick and easy the packaging was amazing like always
