I've been vaping for around a month now and love it. I started with a vape pen but quickly upgraded to a better mod. Currently I'm using an IPV D2 with a Herakles sub ohm tank. It has temp control, which I've yet to try. But the power mode is great. How much difference is there between power mode and temperature mode? I have the ni200 coils but im waiting for my .2Ω coil to go bad before I change it out. Any tips or suggestions would be great. Thanks.
