thank you all. I did read the manual. My husband used to do all if this butt ghee just recently passed away. Im very suprised that it doesn't seem to produe any vape even at 80wt.and the juice spits back into my mouth and burns. I am not new to vaping, i have, right now a reuleax 200, a eleaf istick and my smok skyhook just broke. before my husband passed we had a rda, i guess , on the 200 for dripping. That's really all I want, something i just drip juice into. Any suggestions? I also tried the kangertech dribbox 60 but i really don't want another ' squonker' TIA!
