I received this as a gift from Geekvape. I have absolutely no clue on how to do RDAs. Any insight, hindsight and/or advice would greatly be appreciated.
I'd look into videos on building
rda's, first. Then look at what tools and supplies you have, get what you don't have. You could also go to a local shop, some will build it for you if you buy the supplies needed from them and show you what to do.
Hard to recommend anything else until you let us know your vape style, nic level,
juice types and what tools/supplies you have.
