You can swap the bases that are on the coils and they work great in one another.
The Herakles coil is 9 times better.
Maybe not mathematically 9 times but exaggerationally 9 times.
You know, that random number you just pick off the top of your head......
roger that, Ive been building since my 2nd week of vaping back when the Kayfun 3.1 first came out.
My girlfriend, who was a builder also, swears by the 0.4 herekles coil as the reason she stopped building. I finally tried them, after mocking her for a while. I couldn't accept that a prebuilt coil could have as good a flavor as some of my rtas and rdas.
I was wrong. I still build, because its fun for me. But, damnit if that damn coil in my silo beast doesnt make me ask myself why i spend hundred of dollars on tanks and drippers
