grandson loved it.

This is a fun little build that helps you envision how the earth and moon revolve around the sun and each other. I think the detail on the earth's landmasses could be more accurate. The little strip stickers that you put on ar difficult to align properly. I must have applied mine wrong because the moon phases indicated don't line up with the actual moon position as it rotates. I thought I was careful to align stuff correctly, but maybe not. Stil it's a fun piece

A really fun and interesting build. It's great to have a model where the mechanisms are visible. It adds to the educational value of the orrery. Makes for a unique and striking display model. Hopefully this marks the beginning a trend for more technics other than vehicles of some sort or the other.

The instructions booklet for this is missing steps and pieces necessary for it to work completely. I took it apart twice to find fixes for issues with the gears, and still can't make it work properly. Know that if you follow the assembly instructions exactly, you will not have a working final product. Use the spare pieces and a few extras laying around, and you might get it working properly.

The build is great. I personally would have liked more arrows on the direction model when multiple pieces are being added during a single step but that's not a huge issue. My biggest frustration with this set is with the moon phase stickers provided. The set is only correct for those who live in the southern hemisphere. As an educator I was excited to have this as decor in my classroom but since I live in the northern hemisphere I can't. Because of the inaccuracy of the model I don't feel like it was worth the money I paid for it. I hope in the future there are stickers for both hemispheres.

He enjoyed the gearing and visual of the build. He did wish they had added more planets to the design. He like that it displayed the month and moon phase that was current to today's day and you could change it. He liked the earth was tilted on an angle to make it factual. The turntable below earth and the moon was cleaver.
