I agree with all the prior threads but have found one issue maybe someone can help with. I quit ana's over a year ago and started with the Eluma e-cig and through this forum found my new pv and thanks for that. Bigger batts rock. When I switched to the new supplier found I developed chaped skin in the sinus areas of my face and on the edges of my nose. My first thought was the fluval I started using as a mod. Stopped that and no difference. I thought it maybe an alergy to the rubber. My first supplier only sold prefilled carts of pg only juice. Could it be vg? Hard to believe as it is used in cosmetics?? I am currently using joye 510 cartos and using various juices of pg/vg blend. Anyone got any ideas?? Its still worth the bother but need some input? Tks
