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!

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!

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!
I received product reimbursement in exchange for my honest review. This is a really great Lego set. They said it's really accurate to the Harry Potter story. Great for Harry Potter fans
Super awesome for any Harry Potter fan. My favorite movie and it wiggles
Great set! My daughter has created a whole underworld beneath the castle. Inspired by this this addition!
My 10 year old really enjoyed putting this one together. Lots of fun characters included.
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.
I received product reimbursement in exchange for my honest reviewFirst off I love how sturdy and strong the box is,it is well packaged and the instructions are easy to follow and understand, I’m very happy with this product
