New member here, bought an E-cig for the first time last Saturday. I am down to about 3 cigarettes a day, from about 30. I feel better, and I'm not wheezing like I was. We have been having some leakage problems with one of ours. I think that it is a c-twist style, but I can't find our particular model anywhere (even the store's website). The closest I have been able to find online are the eGo, style with the g50 tank. The cig says ZvaporZ on the side. Anyone familiar with this brand or the type of problems we have had with a similar model? I have been back to the store 3 times with this issue, which they are chalking up to 'user error'. This may be the case, as they replaced the tank, and I am still having problems with it. The problem is, they have not been able to pinpoint what I am doing wrong. Help! I fully expect that it will be necessary for me to give more info about the problem, so if you have a question, just ask! Thanks in advance.
