I'm using the silver bullet 6V e cig. I use the SR punched boge cartos from Vaporescence. They keep burning dry no matter how many drops I keep putting in them. It's like they aren't wicking up the e juice. Does anyone have any suggestions or help for me? I am getting frustrated. Have tried several cartos. They are all the same. I really love this thing when it's working. Just isn't working lately.
