First I'd like to introduce my self, my name is Levisdaddy, i quit smoking 5 weeks ago, on the day when my son Levi was born! I've have been vaping ever since. Started with a green nicotine, but it didnt cut it, i would have began smoking again when i discovered this site. been reading this forum for a some time now and it greatly influenced my decision to purchase an ego-c starter kit. the troubleshoot manual I found to be of great assistance, and this forum has helped me to return to the store i purchased the kit to have them replace the center piece below the tank (the base?). Today I decided to pick up some new liquid and a V3 Clearomizer 2.4 (no LR in stock..), I had grown tired of refilling the cartridge on the ego, and thought this was an intelligent progression. At first i was disappointed with the drag, it pulls slower and it take more effort to get a decent hit. After several hours of use today, and i have used it somewhat heavily, it started to leave a residue on my tongue, with a mild sensation that the liquid was making its way into my mouth.. I did not experience this before with the reg cartridge, even my wife notices that it leaves almost a film on her tongue. My question is: should i desist using it? Where and how could it be leaking, and if it were, would i not notice in the mouth piece. When i wipe it out with paper towel I did notice on only one occasion that a small amount of liquid is in the mouth piece, but after heavy vaping it has not returned, though i still notice it on my tongue. What should i do, any suggestions>? please help, much thanks, look forward to your input and taking part in this wonderful medium for us recently freed of analogs. (smoked 14 years until last month) thank you!
