I've been doing inventory and calculations. I've got enough coils to last me 13 years, plus I'm getting the basics down, but no means a pro, of cooling. If I order 2 liters of 250mg/ml, may have to tap into savings plus throw a few things out of my freezer, I'll have 19 years of nic. I've got a few mods and tanks on reserve. I think the tanks will take some wear and tear. Ive got backup glass and o-rings. It's the mods, I'm worried about. They're the most expensive and when they fail, that's it. I can't afford to stock up on dozens of mods, so I think I need a good mech mod. I don't know why I'm so nervous about them. I was vaping on them in the early days, but you didn't hear all the stories about mods blowing up in people's faces. Anybody got any good recommendations on mech mods?
