- in about 21 hoursAverage rating5out of 5 stars5.0Beautifully detailed setBre77 | 25-34I would recommend this to a friend!Purchased for: SelfOther than a few steps that could be moved around to make an easier building experience, the build was generally pretty good, ending on a production line assembling the 8 solar panel arms, each with eight 1x4 solar panel plates, that would have been much nicer as a larger 2x4 or 2x8 plate. But after all your hard work, you are rewarded with a fantastic detailed set with rotatable solar panels and numerous docking craft for added flare.Play ExperienceAverage rating5out of 5 stars5.0Level of DifficultyAverage rating4out of 5 stars4.0Value for MoneyAverage rating4out of 5 stars4.0Build Time: 3 hrsBuilding Experience: Novice LEGO builderWas this helpful?55International Space Station

(I might super-glue it together for safer handling).February 3, 2020Emily, Customer ServiceWe wouldn't recommend glue! Some glues can be too harsh for the plastic. Plus, if your set's glued together, you can't take it apart and have fun building again.Play ExperienceAverage rating5out of 5 stars5.0Value for MoneyAverage rating5out of 5 stars5.0Building Experience: Expert LEGO builderWas this helpful?55International Space Station
