[This review was collected as part of a promotion.] I wasn't sure why this was labeled 18+ at first, but I understand now. Let me just say it's a beautiful set. Very intricate. You need to be precise. You need to be firm but gentle. My 11yo helped, but he needed us there with him. It took 2 adults and one child 2 hours to complete. We messed up a part and had to go back, which was so challenging to fix. But the final result with the moving mechanism is immense. It's notlw in a hugh shelf away from the cats and the 11yo. I'm afraid to let anyone near it, lol.

[This review was collected as part of a promotion.] I always love reading the little snippets of information that Lego includes in the build book! Super easy to follow the directions. It really “flies”!!!! I can’t wait to display this in my science classroom!!

I had to have this since I purchased the Mona Lisa kit. The flying machine is fairly easy to build and I only got tripped up on something simple when I was securing the wings to the frame. It looks good when completed. For the size and quality, it's a good price.

So I got this one just because I'm a big fan of Futurama. That episode with Leonardo da Vinci is one of my favorites. However I got to admit I've done quite a bit of Legos this one is my favorite. Adding the pulley like system was chef's kiss. This is a good size set for the price. I recommend this one.

I love this set. And looked forward to future sets

Excellent! Make more Leonardo! Obviously his notebooks are full of things to build.

Love the detail and subject matter. I would recommend this kit to anyone.

Awesome build, robust, easy to follow instructions, and the finished model looks great

It’s a nice item to display on a shelf but less suitable for play. Instructions are easy to follow.

I really enjoyed this build. These are the type of Lego sets I like to collect.
