This was a fun build with lots of complexities due to the movements. We build this using "Build together" instructions and everything came together really well. Once complete, the movement is smooth and seems pretty accurate, and this was a great way to learn about how our earth moves around the sun and what that means.

My son loves it and he's 12. This is one of his first Technic heavy sets and it was a little tough for him. He only missed one gear but the whole set didn't work without it. We fixed it pretty easily, and he loves to watch the sun rotate with the moon. We got it for just before the solar eclipse and he loves that it lined up with a new moon on the calendar.

I loved the building experience of this and I love how it does so much with quite little pieces

This is a fun build that does not take to long to finish. It looks great and is quite enjoyable watching the Earth spin and go around the sun.

Impressed by the model in general, the only thing I found funny was how America was printed since the equator seems to go across Mexico

This was my first total Technic build and I was so delighted that it worked every step along the way, and glad that my progress could be checked. I will enjoy sharing the lessons with my granddaughters.

Love the idea. My son is full on into space right now so what better way to get him excited than to build his own orbiting Earth. Looking forward to more sets like this. We love Legos!!

Although not a long build, it was a lot of fun to put together. This is a great display piece if you are a fan of anything space, and the mechanism will amaze you! Once completed it runs extremely smoothly. I would definitely recommend this set!

A fascinate build that is challenging. Excellent design that is a great representation of the interaction between the Sun, Earth and Moon. A great teaching aid for my grandchildren.

After buying many age-appropriate sets for my daughters, I enjoyed the modest challenge this build offered. And they loved turning the gears and watching the rotation of earth and moon.
