Customer reviews
Great experience overall.
Wonderful.
We can conduct our research here. The ecosystem is stable enough. Not ideal, but functional.
The sentient atmosphere on my world is hostile. It actively works against my preferences and makes the environment genuinely unpleasant. Customer service refused to intervene.
The world works flawlessly, but the engineering systems are complex. We needed specialized staff to maintain them. Plan accordingly.
Perfect. Highly satisfied.
