12-year-old grandson loved it!

excellent gift for my 9 year old nephew. He's a very bright child and he loved it.

[This review was collected as part of a promotion.] It was cool to put together.

It was complex to build but a joy for my classroom students to see it in action.

Kept grandkids busy

Kiddo loved it he's 15.

Awesome build

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

The moon phase stickers are wrong and there is no way to rearrange them to the correct order. It would have been simple to either research the moon phases or make the stickers so they could be put in the correct order. It's infuriating. It was pretty simple to build and the instructions are clear. The ratios are pretty good and appreciate that the earth has an axial tilt. Would have been better if the sun was an actual build and not just two parts.
