Drew, just think of it as 7.14 dog years...

Oops, yes, I left one off.
The 510>510 shorty that comes on it.
Then a 510>901
Then 901>510 (or to whatever I want if it's not a 901/808 threaded atty/carto)
I got this combo long ago for a drip shield to work better with 510 stuff. It also gives me a more adjustable air flow.
The first two never come off the Darwin for the most part.
I often go from 901 to 801 as well.
So far I've used all of the following larger stuff on my Darwin and they'll open and close.
Giantomizer 3D
Type A and B Ego T
Vision Deux
Turbine Tanks (Discontinued)
801 atties of course.
Those are all ego sized, so I'm guessing stuff like the Echo, and other 'eGo sized in diameter' would close too.
Come to think of it maybe there is a real business oppertunity here for the over 50 crowd --------------- ...... eliquid, bringing the vape and play to a whole new level
Does anyone use cherryvape drip tips on their darwin? Mine was working fine and all of a sudden it didn't want to close with a cherryvape drip tip so i have to use a normal delrin one or an aluminum one. I might have to buy a Super T Tip for this thing lol.
