Hi everyone. Brand new to vaping. I just got the Sigelei mini with an Aspire Nautilus tank. I've been reading a bit and trying to understand how the ohms and volts effect things and I'm not grasping it all that much. One thing i have picked up on is that lower ohms will be a more tasty vape. True? I know this box goes down to .3ohms but I'm not sure how to get it to do that. Are ohms controlled strictly by the hardware? I know this had a 1.8ohm and 1.6 ohm atomizer with it so i'm guessing that's the case but I'm not understanding then what the Direct (DCDC) mode here is for if you can't adjust anything. I want to try lower ohm but can't get it to do that at all even with direct mode. Info appreciated. Thank you.
