Hi and welcome. I can only mirror what others have said about SMOK stuff. Never had much luck with them myself and their coils are crap. Mech mod wise you really have to know what you’re doing. Lion batteries can be dangerous things in a mech mod if you’re not careful. You’ll no doubt get a million answers regarding mods. Depends what you want. Light and plastics or heavy solid metal mods. Single battery mods aren’t gonna last long sub ohming so you’d need quite a few batteries. Something with two batteries may be better.
