Is it possible to buy 20 bad cartomizers? I picked them up from two different vendors but they are the same brand-- SGS 510s. I've used cartomizers from all four boxes and after filling by either dripping directly in and by the condom method, each and every one of them has had a horrible horrible burned flavor, so much so that I can't taste anything but that. It hasn't made any difference if I fill it and attempt to vape it immediately, letting it sit overnight, and allowing it to sit until the next day. There is still no taste save for the bad taste. Is it possible I had the misfortune to buy all my cartomizers from the same bad lot or do I just need to keep attempting to vape away the burn in the hope that it will eventually start spewing forth flavored plumes?
