LEGO Technic Planet Earth and Moon in Orbit Building Set, Outer Space Birthday Gift for 10 Year Olds, Solar System Space Toy for Imaginative, Independent Play, Space Room Décor for Boys & Girls, 42179

Love the model!! I wish it was more realistic in terms of the number of times things rotate compared to how they orbit each other, but much much larger gears would be required to do it properly, so I understand the design choice. It is a great model - and representative - even if it's not astronomically accurate 🙂 I would definitely bring it to school to show my students - it illustrates the concept well - though I bought for home use: for myself and for my boys. 🙂 Really fun build, challenging enough, but my son still only needed help with mounting the earth and moon so that the correct month showed according to the earth's tilt. 🙂 Good job, Lego! Great set!

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).

I bought this as a birthday gift for a very inquisitive youngster who loves Lego Technic. He hasn't received it yet, but I know he'll love it and I'm delighted that it has such great learning opportunities for him.

Competitive pricing with that other big-name delivery company. But, no need to wait and hope it arrives on time. Besides, the reviews on that other (A) website said that previously opened boxes were frequently delivered. Buying from my Wal-Mart allowed me to get it same day and to immediately be assured that the box was intact and ready for gift giving.

I've had this set on my wishlist for a while now. Every time I see it in stores I just WANT it so badly!!! Finally made the purchase, and I'm so happy! Watching it come together was such a joy...sure, it was a bit tricky (a few times I had to triple check a step) but it looks so cool! Definitely in my top 10 favorite sets!

This was s gift and was very well received. It's a Lego product so it's top notch. Walmart had it in stock when others did not. Their price was very good an delivery was excellent. Would recommend Walmart over ‘the other' guys at this point. You won't be disappointed

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

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

set was good. the packaging was terrible. im pretty sure that they picked the box in the worst condition possible. there had to be a box in good condition but this was definitely picked off the shelf at the store in damaged condition. I saw this same box in the store in damaged condition along with others that were not damaged.
