It seems no matter what I do with the ismoka BCC Coil system that I end up with a burnt vape. I'm also using a variable voltage battery. (which is new to me) I have it at 4.0. I actually bought it a few months ago and had the same problem when I had regular joytech batteries. It seemed if it it tipped just a bit, hanging on my neck with a lanyard I would get the same burnt taste, then I would get one good vape inhalation, then burnt again. So I went back to my regular dual coil cartomizers, smoketeck, with a tank. So now here I am again trying it again and having the same problems. I don't just want to waste money. I've read reviews how other people just love it and I want to love it too. What could I be doing wrong? I push the bottom head all the way down when I put it in and i have the 2.5 ohms heads. Any suggestions? I really like to use a laynard as I would lose my e-cig somewhere in my house and have a nico fit. lol
