That works too. But it's cheaper to build, if nothing else. I dunno, really. I moved into mech mods back in the bad old days when there was no other choice than eGo pens and regulated mods didn't go above 15 watts. I needed more to keep me off the stinkies. If you're a mekkie, building is a requirement; it's the only tool you have to adjust the vape. I've been doing it so long now I could do it in my sleep. So nowadays I use mechs and regulated mods both, but I still build all my own coils

There's a learning curve, certainly, and some outlay at first for tools and parts. But once you have them, and learn how, it is not hard or expensive to do.
