dam some rambling in here.. way off topic which could have been done via private message.
Well I have the #smokG150 which comes with a TFV8 Baby Tank (UK edition) at 2mm, I bought a V8 Baby RBA 'thinking all ways good' but the RBA wasn't quite reaching the chimney once it was all together, then I was advise to get an extender which should have bridged the gap between the chimney and RBA, only now the glass is too short.. Dam SMOK are a pain in the butt.
Original TFV8 Baby Tank
Just the RBA and extended glass
RBA and extender chimney and glass
all descriptions upon buying these items it did say it was for the TFV8 Baby Tank and yet none fit correctly
