As the title states...i keep seeing AWESOME pics of mods with super sweet rba's......found plenty for sale. Yet i'm not sure if i'm pro enough yet to start tinkering with them(Been vaping for almost 2 weeks) I just ordered a gang of Clearo's because i'm familiar with how they work.Excuse the newb question but is there a way to just change the core out on a atty like you would a clearo? If so that would be awesome. But at this point i'm ppprreeetttyyyy sure that you do as the name implies.....Rebuild them. lol So any and all help would be great. I did search but couldn't quite find my answer.....if nothing else can you guys recommend a quirky nice looking piece? I already ordered a pro tank,vivi nova, and a evod. Thanks in advance!
