Very fun set, easy to build and love how it represents above water and below

### ⭐⭐⭐⭐⭐ High quality set
*by L***I on August 30, 2025*

Our daughter loves Harry Potter.

### ⭐⭐⭐⭐⭐ Great Gift, Cheaper than Lego Store
*by S***. on December 13, 2023*

My daughter saw this at the Lego Store at Disney Springs, but of course, it was $10-$15 more expensive than on Amazon. She was okay waiting an extra day or two to receive it. Win-win. None of the pieces were missing. It's a standard Lego product, so no issues there. Happy to have saved a little bit of money and my daughter was happy in the end.
