Well, the Golden Jewels finally arrived in Weedahoma. Beautiful...1st one opened tight, but worked. Rethreading reminds me of doing the same to Wristwatch backs(I worked as a Master Jewelers apprentice part time years ago). Precision fit, yes...practical in this situation, Absolutely NOT.
Loaded one with fresh grown Moby Dick, set ALP for session at 420F(my usual).
It vaped well, seemed quicker to finish than normal, but, ABV was perfectly toasted. Ive opened and used 2 so far. Im actually too toasted to judge at this point.
The idea is great, funtions good as far as Vaping is concerned, but, the Ergonomics Pull a Vacuum! No chance in hell could anyone with Any Dexterity problems use these in current form, IMO !! The Precision threads are kool, but....keyword BUT A PITA !!
If you are a tinker or ritualistic type, then they may be the cats meow
