I have never purchased one before, but to my understanding, and I could be wrong.. The 510 to 510 adapter I plan on using to protect the Provari's
threading from stripping. I will screw it on and attach my atomizers on top of that. I found on some of my other
devices, the threading seems to strip little by little over time from the constant screwing/unscrewing of atties. So I rather wear down the threading on my adapter than on my provari. Someone correct me if I'm wrong but this adapter can be used for this purpose right?
