I'm pretty new to this so go on easy me. I'm about a week into vaping and using my Smokeless Image Volt. I gotta say, I love it! I've smoked 3 or less analogs per day since owning the Volt. Today I haven't had any yet. I bought the kit with 2 batteries and got myself some different flavor cartos. That said, I have a few questions. I placed some orders for e-juice from a few different sites that I first researched in the e-liquid forum. I saw SteelJan's video showing how to refill the cartos. It was very informative and helpful. My question is: Do I save my cartos when they run out for refilling? Can I use different flavor e-juices in those cartos? Do I have to clean them first before switching to a new juice? If so, how? I also find that with rapid and heavy use, the carto becomes pretty warm and the puffs are not that satisfying. They lack in throat hit and vapor. If I let them settle down for a few minutes, the device works properly. Is this normal? I also noticed that if my lip is in the way of the whole when I take a drag, it kind of burns my lip. Is that normal as well? Other than these minor questions and issues, I have to admit I LOVE my VOLT! I didn't think it would be this easy for me to quit (or cut down drastically) smoking. Sorry for the dumb and n00bish questions. Any help is greatly appreciated!
