Well I was very excited to move up to this from the subtank mini for some more cloud but I'm just saddened by this thing. All it does it spit at me. I tried the .5, the .15 temp control, and the .25. Tried on an ipv3li and sigelei 150w. Went through all the temp ranges of each coil, no matter where it's at its constantly spitting. It's ridiculous. Maybe it wouldn't be such a juice chugger if it didn't blow half of the hit in to my mouth. Idk what to do here. I have a tfv4 getting delivered tomorrow from vaperoyalty, and if I have more issues like this I suppose I'll be stuck with the subtank forever. If anyone has any similar problems and how to fix please help me out here. Thanks guys
