I have found one small "occurrence" that can happen with Indica.
It is not a bug, and likely could be addressed if anyone felt it an issue.
I went out into the cold for the first time with my unit today.
I duplicated the occurrence a few times to be sure.
When the temperature outside is substantially cold, and I do a session at red ....
The door becomes a bit loose.
I was outside standing in the cold.
(The Indica makes a WONDERUL hand Warmer)
The door jiggled a bit as I moved my unit around, and then I was able to shake my unit and make the door move a bit.
I was concerned about what might have happened.
Keeping my fingers around the now looser door, I went indoors to warm up
Once indoors my units door was in place and did not move at all.
I went outside, and the temperature difference (Heat expands.. cold contracts)
did not occur at lower vape temperatures... or at higher ambient temperatures.
It was a case of Unit being hot and expanded, while Door was cold and contracted.
Not a problem, and I found an easy remedy for it.
I lay a piece of aluminum foil a tiny bit larger than the door, into the door slot, and then slip the door in place. The door is absolutely snug in this manner, even when I vaped at RED while outside in cold.
EDIT:
Please note: I am not reporting this as a complaint or a bug... it is just science.
I am delighted to pack this "arrow" in my "quiver" of tools!
