I think a few folks are using those mods. I think the consensus was it's great in wattage mode, not so much TC (although, I'm not sure the folks who have one necessarily wanted a TC vape). I think it's fairly well liked, maybe some of those folks will come across your thread. I don't know a great deal about the mods and the differences between them, unfortunately. I'd say the manufacturer's page is as good a place to start as any. Best of luck, and welcome to ECF.
