If I would have found GH a few years ago, oh man. I quit cigs a few years ago. I've actually been nicotine free for a while now. My first 'big battery' was a 808 Ego paired with a monstrous dual coil cartomizer that held around 6ml. My last device was something like a Magneto mechanical mod only it had the extension tube for 18650 batteries. I think without the extension it used a 18500. I had a few 18650 2,000 mah batteries, the kick for variable wattage/circuit protection, and a few bottom coil tanks. I loved the bottom coil tank system. But finding a bad coil was rough!
