There was fog on both side of the glasses after standing by for 20 mins in door.
This situation may happen under certain environment such like high humidity or too cold place. Turn off LUNA and place it in a dry place will make the fog disappear, dehumidifier will also help.
First of all, thanks for your support and feedback.
We're sorry to see that happen. Depending on different humidity level and weather, it might happen on quite a few units of LUNA product. We're investigating this, and also notice our manufacture to understand the possible issue. We'll get back to you once we get more detail on that.
I guess the assembly line got pretty high humidity.
to fix this might need to break SEAL & dry the interior structure & re-seal it..
