Yep, their basic (least expensive) 100mg/mL nic (currently $45/liter). Link (red highlight) in my previous post.
That was 99.9% my fault. I linked the product to my own slang. I apologize for my needless confusion.
Concerns?... ah, no. Experience?... only once.
That was (at the time) a $140 DNA 40(?) Vapor Shark.
It was my first "splurge" vape purchase, and I was using a couple of different tank atty's on it, for about 9 months. To my own culpability, they were all proven leakers, and I have no one to blame but myself.
But... the screen died, and I could not resurrect it.
My judgement comes, from the fact, that I used those very same tanks... had completely "bricked" two other mods (not just a dead screen; but the would not fire) , on an e-Leaf and Segelli... yet resurrected the latter two with a simple PGA soak (followed with a thorough dry).
Since that time; DNA boards, and $100+ mods, can all kiss my rear end! <insert middle finger to every uppity mfg. gif here>
A bit off topic (maybe, kinda, sorta, not really?); use
only hardware you are
very comfortable/familiar with, for flavor testing. Otherwise, you are not going to be certain whether the perceived flavor is the result of the hardware, or the concentrate.
By my reading of your posting; I wouldn't know if the result/flavor outcome was due to the wicking, atty, or concentrate.
Ideally, one will do testing on equipment, as close to what one's daily set-up is. Barring that, one would (ideally?) use hardware that can emulate that as much as possible.
Using new/unfamiliar hardware, can only be uninformative (for that, and any other hardware).
(based only on my own personal experience

)
No small accomplishment! I hope you are proud of yourself!!
