The post you’ve quoted was from April 2017, much has changed since then. I have the RBA and the necessary glass for the Big Baby BeastI wanted to get the RBA for the v8 but if getting a spare glass is this hard / complicated ,I ill rather upgrade to the SMOK S priv [little ''young'' for my taste ] or the new MAG 225 with TFV12 PRINCE[ very gangster-ish, but cool] . Can / will any of the '' WISE ONES'' give me some pointers , I like the SMOK brand and hope to stay with them - OR - sugestions for a nice KANGERTECH please ?
As for recommending an upgrade, it would be helpful to know what your requirements are and what your budget is. Are you looking for a stock coil tank, do you want to build your own coils, or a bit of both?
And, I can’t think of a nice kangertech, the last decent kit they did was the Subox Kit, nothing since then.
