Absolutely, that's why I said...
Incidently, because I know Ohms Law and battery safety, I am curently running a .24Ω build and have built as low as .18Ω.
Thanks...Yeah me too but I don't care to run below 0.5 on my mech. Not saying that an expert builder can't or shouldn't. Being informed enough to understand the risks is wise, imo.
Now the dna 40s are a whole other matter....with nickel build on a regulated temperature control device you really have no other choice but to build in the very low subohm range. Of course, I am not saying anything here that you don't already know, oh king of vapor flask....
The scary part is jax that there are folks that have builds made by a shop or by themselves but are sorely lacking in the understanding of ohms law. Also, we can never really be certain of what process that people are using to build subohm attys. Iow, how are they checking builds for stability?
Then there is the accidental firing possibility.
I would venture to guess that when you run that low, you are very much heads up to your battery life and lock status of your firing button.

) I feel pretty safe in their use.
