Wonderful for STEM lovers!
This is my favourite set that I have built. I loved all the different details, I especially appreciated the hidden ones. The bee was a little fiddly and the app was more helpful to complete bee compared to the book. Once built, it is colourful and lovely to look at, as well as a great talking piece for visitors.

Very good set for 18+
[This review was collected as part of a promotion.] It is a very interesting set of Lego. I was expected to complete this in a night. Yet have not done it. My fault! It has many parts that packed together which make it easier to assemble. It is for 18+ though. Definitely good for brain logic practiing and skill and pay attention to details. I would love to have to time complete this set soon.

Amazing influence for kids
[This review was collected as part of a promotion.] This set is absolutely amazing! My nephew loves legos and isn’t the most fond of school right now. I’ve been trying to get him to love to learn, with fun books, cute flashcards, and I didn’t even know Lego had this STEM set! This can be inspirational for younger kids and is so important to have.

Fun set
[This review was collected as part of a promotion.] This was such a fun set to put together! Lego always makes sets that are amazing quality with easy to understand instructions. My little sister helped me put it together and she loved the bee

Must buy for science fans
[This review was collected as part of a promotion.] This was a fantastic build, and looks great when displayed! There are so many fun science references throughout the build (some hidden). Lot's of great micro build throughout, and it comes together as a whole piece nicely. I really appreciate how few stickers there are (only four), with most images built into the pieces, as I hate having to place tons of stickers and inevitably not centering them great. Probably one of my favorite builds I've done yet, and a must get if you're into science.

A blast!
[This review was collected as part of a promotion.] This was a blast! My fiancé and I completed this in about an hour and a half, with some extra time to get up and get coffee. The instructions were extremely clear, and the finished product is adorable. The only thing that I noticed was missing was a single, small piece to complete the car. We kept everything organized as we worked, so I don't believe we lost it. All in all, this was a lovely activity to do on a rainy day.
