It’s very cool looking and works better then I imagined, the solar system was a nice bonus as you were able to spin it

Excellent for a little Space or Science Enthusiast
My 7 yr old son loves everything about space. He researched this lego set and asked for it as an end of term reward. He was not disappointed! The set is small but offers opportunities to enhance building techniques as well as encourage engagement in imaginative play. All three builds are creative and entertaining.

We love legos!
[This review was collected as part of a promotion.] We love this Lego set! My daughter is big into space so she was super excited to build this together. It obviously goes together flawlessly and effortlessly. The light up brick was so cool!! Unfortunately i was unable to get a picture with it completed before my daughter wanted to take it apart and build it another way lol. Overall, it’s amazing!
