Most of the time its a faulty coil that causes the leaking.With a high VG chain vaping will cause a burnt taste because a thicker juice can't wick as efficiently in a clearomizer like the Nautilus
I've been vaping for a while now and I only do 6mg nic.But at times I need a little more nicotine.The next time I get some juice I'm going to bump it up to 7 or 8mg.I mainly drip so going above 8mg is a recipe for chunking a lung out.
My deepest condolences. Its never easy losing a loved one.I understand your frustration and I don't blame you for how you feel right now.Keep your chin up man.Very sorry for your loss.
They are ridiculously heavy.I put one in my pocket at my B&M just to see if it would be a pain to carry around and it nearly pulled my basketball shorts down.lol it's like a damn boat anchor.I have heard they are workhorses
