Visualize a solar eclipse!
Put a flashlight on the sun, and you can see the Moon’s shadow cast on the Earth as it orbits! I am in love with this kit. Every few days I’ll turn the crank. It’s a little joy, watching the seasons change.

Out of this world
Bought this to show granddaughter about motion of earth, moon around our star. Really enjoyed the build and it all works very well. Very educational and fun.

Really enjoyed this one....
My second Technics and a much different experience to the first one. Firstly, it works - ignore what anyone else says, if you follow the instructions everything rotates. Secondly, it's very stable - admittedly i was a little uncomfortable as I connected the earth section, but the extra struts afterwards keep it solid. The instructions aren't always the best because they don't show from multiple angles which can be needed in odd cases when connecting sections. I admit that I put one section on upside down and it was only 10 pages later that I realised something was wrong, luckily i didn't need to undo too much. The size of the bags was better than Mars Rover, so was able to much more easily find the pieces I needed. My only gripe is that the sun and earth do look a little 'tacky'; but i was half expecting that from feedback i'd seen before purchasing. Other than that I think it looks good. Didn't take me too long to build, built across and afternoon and the following morning - i don't time things but i'd be surprised if it were more than 3 hours (4 max).

Easy to get wrong, tough to troubleshoot.
Lots of opportunity when building this to make a mistake and press on, not unusual with Lego to have to correct as I go, but this came apart and went back together more times than any set I have made. The sun and earth are of disappointing quality. The idea is ace…. Be cool if it expanded into a solar system with an add on. This feels like a rushed idea, which is sad given the high level of engineering inside. There is not much play here, turn the handle and it moves…… Possible my least favourite and most disappointing set

Awesome product, but...
Don't get me wrong, it's an awesome product. Building technics, the design and educationnal purpose is realy good. However, the labels for the moon phase are designed for southern hemisphere only. No mention about it in the instruction nor other labels for northern hemisphere customer. Not possible to invert them somehow. Moreover, the model lack of stability. But overall, I recommend it, but be aware of these 2 major points. Thanks

Amazing Set for a Little Space Enthusiast
Got this set for my 5 year old, she really enjoyed how the whole thing came together and the gear work in it. She was really happy to learn more about the solar system, had a long discussion about it after building the set.
