smok used to have a really terrible rep. Like by far the worst in the industry terrible. To the point of seeming like a scam. It was build quality though. That sort of thing is fixable. You have to do it though. How long are smok mods lasting NOW? Anything under a year is “still terrible” 1-2 years is “some improvement but not great” where anything more than that will be “actually pretty decent now”
