Yep, they took a lot of heat for the unknown wicking material in the original BVC coils. Some postured they were a ceramic something or other and people were afraid they'd be breathing in harmful materials. But when they're wet, there's little to no chance any of the material could become airborn. I was never really concerned about them. I stopped using them because I was tired of buying
tank after tank from Nauty that leaked and was poorly made to begin with. I was resolute in my claim of never getting into building no stinking coils. Nope, not me. Nevah, for sure. Then like what we see with Zen's Kabuki, I read all these love poems to all things Kayfun and I finally broke down and bought one. Oh and of course, I bought a zillion other things, like ohm meter, coil building thingamabobs, cotton bacon, kanthal, tools a plenty. And I started building. I've gotten good at it too. Yes I have, but there are times when I have wished someone would make a system that was machined and built like a Kayfun, that made great tasting vapor and didn't require me fussing with electricity. Looks like the Kabuki just may be that top. Yes it just might be........
