Incredible value!

By LegoMasterDJ

from San Diego

Comments about LEGO Master Builder Academy Builders Invention Designer (20215):

My daughter (and I) collectively own several different Lego sets, and I must say that this is by far my favorite. This is an awesome Lego set, designed for more experienced builders or even adults. Since this kit was relatively expensive ($80) and that this was my first MBA set, I looked around carefully to choose the right one that is appropriate for us to play together. At first glance, 675 pieces for $80 seemed steep since I am used to dropping around $50 for a Lego set but I must say that I am thoroughly impressed with the value of this kit, so much so that I will likely purchase additional MBA sets in the near future. Once I opened this kit I realized how special this set is. This kit comes with 3 very nicely printed books (on high quality stock paper) with detailed instructions and techniques for building different creations. I also learned that in addition to the 11 different items you can build, you can also unlock/download 22 ADDITIONAL instructions (from to build even more items including vehicles and architectural structures! That was a huge, pleasant surprise for me! What other set can give you 33 different builds in a single box??? The color palette for this set is much more mature, with the navy blue/beige/black tone which is super classy. If you are a fan of Legos, this is an absolute must-have! Also note: My order arrived within 4 days by FedEx, which was also very awesome. Enjoy!

Unique in the world of Legos in style and theme. I love the colors and special pieces, and the versatility of what all you can build with it. The set comes with several instruction books full of really neat things to build from it. I would definitely recommend.

Pretty Impressive Presentation

By rsearles80

from Cleveland

Comments about LEGO Master Builder Academy Builders Invention Designer (20215):

The builds for this set are fun, but I can't say that they'll stay put together as long as some of the other things in my collection before getting scavenged for parts. For example, I'm not sure what sort of long-term use I'd have for a time-travelling doorway that's a set of Roman columns on one side and a Japanese temple on the other. But the presentation for the set itself is pretty amazing, and definitely won me over. The included books are high-quality and informative, with both real-world and Lego-based history lessons. I love getting the how and why behind the inclusion of certain parts as I'm building, it's a nice upgrade from the usual pictures-only instructions and has really stretched the amount of time I'm taking to build the included models. The extra instructions for alternate models are great as well, my only complaint there is that the set includes so many unusual specialty parts and it's frustrating at the moment not being able to build more than one option at a time. The higher than average cost of the set is certainly justified due to the books, but makes it prohibitively expensive to buy two for building the alternates. All in all though I'd say that my experience with this set encouraged me to pick up the other MBA offerings as soon as I can, as it's worth it just for the books and the variety of interesting parts that I'll use later down the road for bigger projects.

Great set, Not a great value

By Kday

from Chicago

Comments about LEGO Master Builder Academy Builders Invention Designer (20215):

Having extensive experience with Lego and Lego Education products I find their newer offerings to lack the quality and thoughtfulness Lego previously offered. The other Lego MBA kits came in similar box sizes and with sorting trays. This set comes in a box approximately twice as wide and without any sorting trays. So you end up with unsorted pieces haphazardly thrown into a box that is way too big for the set, that takes up a lot of space.
