Well I got a "BADA-BING" yesterday (not from puresmoker because they where out) and I have to say I am really disapointed, I think something is really wrong with mine as it only produces a very small amount of vapor, I have two batteries and they both do the same thing, maybe I will try a dif BAT but I think it is the atomizer :\
It took us about 5 or 6 min to get some good vapor. We dropped 2-3 drops liquid on the atomizer and then puffed a little. Then 2-3 drops again then puffed again. Repeated for a while until the vapor picked up. Also... primer puff helps (little puff 1st then big puff). Takes a good 5-6 second puff to heat up enough to get the megavapor. If that doesn't work.. must be the atomizer. Not likely that both batteries would be messed up. Did you charge them up for 8-10 hours first?
