So I ordered a pack of XL black (not see thru) fluxos from gotvapes.com. First Ill say I think how you have to go about filling them is not at all user friendly, not even possible at least for me without an actual syring. I filled them up with about 45 drops, let em sit overnight. And no matter what after a couple good drags they taste )like crap(burnt) I've tried taking out the thin and first rubber gasket before the filler gasket, I've heard the burning iws the silicone being singed, still problems. I've searched for a while with no answers. Anybody?
