But I did find a few laying around from a few months ago that I am going to use until I can locate some originals or a good alternate. I did find an actual ST pre-punched tank carto and have that one going right now and it is working great so far. Looks like I may have to grab some Kangers or try the Ikenvape cartos, but I heard a lot of those are selling out quickly..
I have used kanger style bottom coils in the past and did not care for them. Ikenvape products do really interest me. the the cartos are half the quality of the i06 attys, i think i would still be very happy
I know that Tar has mentioned he has got Boges from Sam and is very happy with them. Maybe right now its a just a luck of the draw and where in the production lot your cartos came from.
