I've been using regulated devIces since I started vaping.. I went from ego, to mvp, to dna 30, & now I'm sub ohming on a sigelei 150w. I really enjoy the vape I get off of it, but I'm somewhat interested in getting a mech. Maybe it's just the aesthetics.. They look so cool to me lol. Could some of y'all give some input on why you use mechanical mods & some of the advantages and disadvantages of doing so?
