I'm a new member but have read hundreds of threads on here. My wife says that I am obsessed with vaping. I might just be. I have been analog free for 2 1/2 months now. Went from a 510t to a old goat mod (stopped working) to ego batteries with the j-tank and kanger horizontal coil cartomizers. One stopped working after maybe an hour but the second one is still going. Is anyone having good luck with these carts. Let me hear some opions. Need some advice for punching holes in the carts too. Size nails ect.
