So much fun!

I was super apprehensive originally due to the price but ended up purchasing on Insider release day. I spent a full day building this and couldn't put it down until it was finished because it was such a fun set.

Overpriced

This is not worth the money. Sets like this would normally be 25-50% cheaper than this. I think LEGO is testing to see how much they can make for new style sets. It looks good and it's fun to make but the price makes it painful.

Awesome Set

This has been an amazing set to build. SO many interesting mechanical parts and such a creative design. The Tropical Aquarium is by far my favorite set so far. Lego design team - please create more colorful and creative sets like this for adults. I would love to see a colorful line similar to the Friends theme, but for more complex for adults.

Beautiful

This is probably one of the prettiest sets I've ever purchased. The moving pieces make it fun and entertaining. It has a lot of fun details and some that still make me smile and laugh a little when I see them. It's a little on the pricey side but was worth it in my opinion.

Amazing!!!

I love love love looooovvveee this Lego set!! I think it is 100% worth the money. It has so many moving pieces. The instructions did get a little hard at times but overall 10/10. The biggest Lego set I had built before this was the Lego cats and this build only took me 18 hours! Such a pretty and amazing set you can tell Lego really took their time with this one!

One of the most Stunning Sets!

This is one of the most innovative and stunning sets of the year. While the price tag is high, it is an amazingly fun build, with some great interactive play pieces, and is visually stunning. This set isn't for everyone, but my son LOVED this build experience, from start to finish, and that's all you can ask as a parent with Lego.

Wonderful design

This design is wonderful, it was such a pleasure to put together every piece was especially beautiful to put together and the fullness of the setting was a masterpiece I really enjoyed every step. It has going back and look at my work and the grandkid loves it as well.

Fun Build

I enjoyed building this set! My husband and I received it as a wedding gift, and it was very relaxing to work together on this project. We have a beautiful display for it. I also enjoyed jumping around to different sections of the set, each bag presented a new challenge and nothing was repetitive.

Very creativd

So I paid for my wife and her friend to fly first class to Europe for a Danube river cruise. The least I deserved for that was an expensive Lego set. To get to the point, this is a great set. I'm through 36 of 41 segments with no missing pieces. The overall build is not repetitive but some of the flowers require a degree of repetition. The colors are what make this such an outstanding set. Everything fit, everything works. Compliments to the creator/designer of this set. It certainly is creative. It's worth the price.

Awesome set, the price is what it is!!!!

The price is what it is! The old saying goes if you need to ask how much it cost you probably can't afford it anyway! I haven't built a Lego set in over 30 years other than kids ones. My 6 year old and I had so much fun building this set it made it worth it to our family. Colors are great, so many moving parts that I had no idea were in the set. Yes there is some wasted space, they could have probably included more stuff off of the front frame or maybe even clear side pieces to make it more “authentic” but this was fun to build. I marked it a 1 for playability only because I don't think this is a set you play with. This is a display piece. The instructions make this so easy to build, thank you Lego.
