[This review was collected as part of a promotion.] The interactive set makes it easy to understand different concepts like the orbit of the Earth and the Moon, the Earths gravitational pull and how the rotations affect the seasons.

Great Product, looks like it would be good, but a gear mechanism doesn't work, I was very excited when I bought it, and now my hope has crashed to the ground.

Me and my son had so much fun playing with this set!

It was really fun, but a little hard to build. I'd suggest this for people who are maybe 13 and up.

I have it at my work desk as a display piece and it's a huge hit in the office!

Looks amazing. Part of my practicing. Looking forward to the assembly.

Gave him a challenge which is nice as most of the time he builds stuff very quickly

Fun to build. When assembled does not turn. Working on where its binds.

This was super fun to build and the after look was great. I loved all the little detail Lego made and they did a great job. Highly recommend.

so stupid it sucks so bad someone should've seen to structurally supporting the sprockets
