I've had no heat issues. Yes the rda and head heated up after chain
vaping .5-.3 builds but to me it was no different than my mechanicals while sub homing. When
vaping at low ohms I set my display to temperature and check it every once in a while. But I have had no problems. For me it was either buying a ipv2 and a bec pro together or only buying one provari. Although the provari is nice it was not flexible enough for me because I use tanks, rda, Cartos at all different ohms. I bought my ipv2 and bec pro together and I'm loving life.
