The temp stays rock solid. If it's cooling down it's not indicating it anywhere.
Since you know it's happening to some degree either the senor is not responding in a timely manner of (IMO more likely) it's not being displayed. This is called 'masking' or sometimes 'window masking' in the industry. You see it on other vapes, the temperature rises a degree or two at a time until it gets near the target, then suddenly jumps to exactly the target (even though it can't be there quite yet).
Otherwise customers might get obsessed on unimportant, strange as that idea might be.
Thermodynamics is a strict science. The rules are laws, always in effect. Heat flow (like taking a hit) automatically means a temperature drop where it matters, detected/displayed or not. I did a series of tests on Ascent, another glass lined conduction vape. Here's one at idle, their 400F agrees with 'my' 399.9 pretty well?
Here it is again a couple seconds (enough time to lay it down and grab the camera) after a heavy hit. Notice it's dropped 40F (I could get as much as 100 degrees! To 300F in heroic hits):
Notice the display on the unit still says '400F'........
Do yourself a favor and don't order until
@OF weighs in.
Thanks for the vote of confidence, but don't hold your breath as it's likely to be a while before I get an Air II to check out (I tend to be careful not to get into discussions not backed in experience.......). Until then my advice remains 'stick to the factory 18650. If it can be confirmed the
exact same unit can be bought elsewhere that should be fine......who's in the position to certify that? Recall I supported buying replacements from Centizen for Air I? Same here?
They work good. Don't do what I do. I take stupid chances.
Love it, 'another self realized man'?
What's the old joke about 'what are the last words of 3 out of 4 redneck teens?'. "Hey, y'all, check this out!".
Regards to all.
