I received product reimbursement in exchange for my honest review. This was a fun little Lego set. I really like the colors of the pieces. Everything is well put together for you. It comes with a step-by-step instruction manual and 4 packets of pieces. I enjoyed putting it together and know that my grandkids will love it!

Awesome Lego set for Harry Potter fans!

I received product reimbursement in exchange for my honest review. My kids love Harry Potter and they love Legos, so this toy was a win-win! They enjoyed putting it together, and it took about 30 minutes. They have been role-playing and acting out scenes with the mini-figures ever since. I love that this set comes with so many mini-figures! Five in fact! The details on this set are so awesome! I love the shark head and the goblet of fire. I would absolutely recommend this super Lego Harry Potter set to any fan of the series!

Fun Set
27 March 2023

I received product reimbursement in exchange for my honest review. It's kind of surreal that Lego is still making Harry Potter sets just like the ones I got as a kid. This is a fun set! The underwater idea is neat, especially with Hermoine and Ron "floating" on the chains. This set includes some fun, interesting pieces too!

Impressive little set!
27 March 2023

I received a product reimbursement in exchange for my honest review. This LEGO Harry Potter Triwizard Tournament was a lot of fun to build. I frequently get sets that I build together with my kids, but this is the first time we built a Harry Potter set. There were a lot of unique pieces and features inside the set that made it interesting. My kids especially liked the unique character pieces. Instructions, as usual for LEGO, were clear and easy to follow. I would rate this as an easy build, but it did take a little bit of time. I think we might be adding more Harry Potter sets to the collection in the future.
