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

    • Great experience.
This build was fun and quick. Plus, the set looks great on my shelf by my modular Hogwarts castle MOC. I wish there was more underwater elements, but overall the set is very balanced. The flip feature is a bit gimmicky, but I could see how kiddos would enjoy it. Overall a delightful set. Although rare, my set was missing one piece. As expected, Lego replaced the missing piece promptly. Definitely recommend. ... show more

    • Great Gift, Cheaper than Lego Store
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. ... show more

    • Kids Love It!!!
I bought this for my granddaughters. They had a ball putting it together. The pieces are well made, and we didn't find any plastic flashing on any of the pieces, so they took care in their cleaning process. on other lego sets I have had to trim the flashing, so the pieces fit together. The granddaughters loved it, so I'm happy. ... show more

    • So cute but not very big
Review Image by Josh & Mal
My son is 10 and he’s a HUGE Harry Potter fan. He is also an avid Lego builder so of course we had to install shelving for all his Harry Potter legos! This is one of HP Lego sets he got for Christmas, he built it within maybe 2 hours if that, so it’s not very large. Idk why I thought it would be a bit bigger, the price does reflect the size. Regardless he’s extremely happy with it! I think it’s adorable 10/ 10. ⃝⃤9¾∞ϟ△⃒⃘⌁☍❾¾ ⚯͛ ... show more

    • My Grandson Loved It!
My 12 year old grandson Loved this present! We gave it to him at his birthday dinner and he was so intent on finishing it that he had it put together before we left the restaurant. He loves Legos and Harry Potter so thus was the perfect gift!
