Hello I am vary new to this concept, I wanted to start vaping as a compromise between me and my non-smoking wife. When I started out I had tried a few brands from places that let you try out their stock at tattoo conventions and such. When I finally decided to invest I needed something cheap but effective. So after some research I went with e-cig.com's E9, I do enjoy the vapor and two batteries alternately charging give me a days worth of vaping. my problem is all this info in review like people say i find it best vaping this e-juice at 5 volts. what on gods green earth dose that mean, I want to get the best vaping experience possible and I'm looking at e-juice now because I like my E9 for now anyway but the pre-filled cartomizers came with marb flavor and its nasty to say the least. As such I am still smoking analogs I'm down from about a pack a day to about 5 a day and I smoke rollies so its an estimate. I am trying to figure out what is the best way to go. The manufacturer of the E9 says its compatible in all parts to the greensmoke and smoke51 products. if that helps. so what is the question here, can anyone help me to figure out what the specs are for what I'm using so it will make more since when I read the reviews.
