With prebuilt coils, you tend to get occasional duds.
I don't build duds
.
I can build to suit me, and with a $4 roll of kanthal I can build hundreds of coils, anytime I want.
No waiting for vapemail, no driving to the B&M, no middle man markup.
Life is expensive enough.
I get it that some vapers will pay for the convenience, I understand some cannot build their own coils for a number of reasons...
But some of us prefer the option, and don't have access to coils unless we order online and wait.
An optional RBA deck would make any of these tanks a viable choice for every vaper, not just the ones that buy prebuilt coils.
Just my opinion.
