I got my first unregulated mech mods. They were in a clearance bin, five bucks per mod. I plan on going over all the points to safely use these. I'm new to this type and wanted to ask a few questions. Are these a decent device to start on? Do you have these or have you used them? What kind of battery would you put in these if you had em? Should I throw them away and get something else lol? Can you point me to some decent 22mm RDA's that would work well on these? I haven't really gotten into rda's in my time vaping. I use Griffins and an Avacado on regulated mods. So I can build decent coils. Any help/info is much appreciated.
