As a big Harry Potter fan i was on the fence initially about these books. I knew I would get them but I wasn't sure if I was really in love with them. One plus point for me is that each Moment is based around a class that is related to one of the houses and this reflected in the minifigures included and the overall colour choices for the book.

Potions - Slytherin

The book itself is quite small and falls somewhere between A6 and A5 when compared to actual paper sizes. I did think they would be slightly larger based on the box size. However, there is so much detail included in each classroom that I found I soon overcame the slight disappointment I felt on their size.

The Potions Class opens up to a full classroom scene that relies on it being laid out on a play surface. Incorporating a blackboard with potion ingredients, shelving with a range of supplies and a host of little bits and pieces. Of course it has some classroom furniture so Professor Snape can teach Seamus and Draco. The way this particular Classroom is constructed means it splits in to 2 separate areas and this is really effective. The detailing on the "spine" wall is exceptional and even incorporates a nice stylised snake.

I was surprised at how snuggly everything fits back in to the book so that you can fold everything away in true playset fashion. Unfortunately, the minifigures do not fit in to the closed book so they do stand a high chance of being separated from the set.

My favourite display option is to have it open as the full book. If you have all 4 of the series they do link together in to a circle which makes for a fun look. It does take up a surprising amount of space though.

Overall an entertaining take on the Harry Potter franchise that was fun to build and offers a good balance between playability and display. This is probably my favourite set, but it is close with the Hufflepuff offering!

When the dreadful year 2020 ended as the clock struck 12, the first thing I did was log onto LEGO.com and order all four classroom sets. I just had to.

So much nostalgia with this set. If you're in my generation (just turned 31), you probably grew up reading Harry Potter books and watching the movie adaptations as each of them came out. I still remember the excitement when I saw the coy tabby cat perching on the teacher's podium in the Transfiguration class leapt and, to Harry, Ron, and all of our surprise, transformed into Professor McGonagall.

Very cool that the set can be neatly folded into a book and shelved for display when not being played with. I just wish that our favorite registered Animagus was paired with her feline self since we already have Scabbers, or Wormtail, included in the set, which could have created an interesting cat and mouse scene.

My set did have an error—it came with two identical printed plates as shown in the picture. I ordered a replacement plate without the print, but it hasn't arrived yet, which is why I haven't applied stickers #9 and #10 on the right side of the classroom, or inside the back cover of the book. When the replacement plate arrives, I'd love to unfold all four sets, place them on a rotating display table, and immerse myself into magical education.

I was looking forward to this set, not because I am a huge Transfiguration fan - which I am not, incidentally, but because McGonagall has never so far been offered a classroom, at least not in the latest Lego series. It is a nice set, but that's about it. Love the idea of the four books, but it is hard to get Transfiguration right, since it's really actually 'only' spellwork, like Charms. I was actually hoping (against hope, as it happened) to get a cat version of McGonagall. Her taking her Animagus form in the films (that is not how it is in the book) for the first lesson is iconic if not canon. That is my big disappointment. However, the design of the set is very Gryffindorish and I love the blackboard and the wall along the book spine. Also the fact that McGonagall has hair. That's a really cool thing.

I think it sort of fun that the actual veraverto spell is used on the board to turn a frog into a glass and not a rat as it is in the story, but the rat is there too if one wants to carry on without variations. Plus a yellow frog is not exactly the most commonly seen Lego frog :)

On the whole, not bad, I'm not over the moon, but I am overexcited to build Potions and Herbology (those are my favourite classes along with Care of Magical Creatures).

Pros: I like the Hogwarts theme and the look of the completed classroom. Putting the individual parts together was a relatively easy experience.

Cons: Connecting any of the internal classroom parts to the book itself was a horrible experiance for me, I am still trying to get it all to stay where it is supposed to and I have been at it for a while now. The book should have had a better lego design for attaching things, they end up very loosely attached and frequently the pieces you are trying to connect to the book come apart as you try to attach them. When you have built everything the instructions tell you how to how to put everything into the book for storage, this is the part I am stuck on. Every time I try to store the chair, and potion cabinet, the rest of the classroom disconnects from the book. Then the book comes off its very weak hinges. On top of all of that, the table is supposed to go on top of the book (connecting to a block at the top) and it causes the whole classroom to disconnect again and the chair and potion cabinet to disconnect.
