I'll chime in here. I've just started with cartos, and I've only used Smok brand. I've also only tried the dual coil variety, double and single punched, only tried 2.0 resistance. I'm actually not too disappointed with these, but I yearn for better, because I know that there is a better carto then these. I don't have a major complaint, mostly just kinda bothers me with the after taste somewhat. The flavor tastes great and all ususally, but sometimes I get a little funky after taste. I dunno, just chewing gum helps a ton.
Okay, so I'm gunna be ordering new cartos fairly soon and I'm trying to research them to make an informed decision. It sounds like you found what you like, a single coil boge huh? Well, boge is what I was thinking of going with as it seems to be more well known then say the Ikenvape kind or the cloud maker kind. By the way, whats SVC stand for? a link would be cool. Sorry to kind of thread jack here, but anyways I'm on the same quest to find the best carto possible. At this point, I'll do more research and wait to hear back from people. Right now I'm leaning twords trying boge. People seem to have good success with those.
