Customer reviews
Used the professional demo to test our building designs against real environmental data. Saved us from three architectural mistakes. The validation alone was worth it.
The rain forest ecology with managed canopy layers is perfect for our research station. Biodiversity actual high, climate stable, everything thriving.
My hollow demonstration planet arrived perfectly. The interior cavern system is lit with bioluminescent crystalline formations that shift color with the seasons. It's become the centerpiece of my collection.
Disappointed. The polar ice world's refrigeration systems failed after two weeks. Replacement process was slow.
