I have a kangertech kbox nano, and 0.2 ohm replacement coils (disposable atomizers) and, when I screw them on too tightly either it will register but after firing it will display 0.0ohm, or it won't register at all unless it's loose enough to, preventing the guard from being screwed on over it, so I'm wondering why they won't work? the only difference that is apparent between the atomizers is that the ones that came with the kit are labeled 5i and the replacements labeled 5k, I can't find anything online about this and a website said nano is supposed to fire 0.3 (what it reads when it does register) 0.5 (0.6) and 1.5 (1.6) all of my atomizers register a point above their resistance, which I believe is normal... what do I do?
