running high ohms is extremely inefficient, i honestly have no clue why people still run anything over 2.0ohms nowadays, other than the fact that they dont want to/afraid of trying something else, you get uneven vaporizing of eliquid, which has no heat, and has hard time of wicking keeping up with unless you are running your power super low and take like 20second drags, its just terrible.
to be honesty i highly suggest you trying at least 1.2-2.0 ohm coils, you would 100% enjoy it more than vaping on a 3.0ohm resistance carto, and if you dont hell, ill send you my solara DNA30 that I dont use for free. im that positive that there is no reason for anyone to be vaping 3.0ohms right now unless they are really that stubborn or scared to try something new. It doesn't matter if it works for you, there are better and more convenient ways to vape nowadays than a 3.0ohm carto tank. taking 10s+ hits on a ecig is just abnormal, we never smoked cigarettes like that, and we dont breathe like that.
that's not true at all.
Sounds like something someone who only uses 4 volts and thicker wire would say.
What is inefficient is running low voltage.
The reason vape stuff runs on such low voltage - 4 volts - is that is the voltage of the batteries we use. It is because we use such low voltage that we also end up using low ohms.
