Nope,still jumping,I've changed the coils too from the ones that came with the RBA,my CoilMaster tab can barely heat them up and is showing some kind oh hot error. I put two 0.4 ohm pre made coils in that I know are good. My RBA seems to keep screwing into the base a long way down. I would love to get this thing to work but I can't see it happening,I'm really disappointed with this one because I have two TPD 2ml Baby Beast tanks that came with kits,I just missed the pre TPD version which is a bloody shame.
