thank you, dears
Well, I hate the idea of fiddling with coils, and I know for a fact that I will hate doing it and I will never find it enjoyable (I despise fiddling with tiny little thingies and I cannot see them either, wearing glasses for being nearsighted and now getting that old-age farsightedness on top of it, so I cannot see it with my glasses and I can no longer see it without them, either) - but then I will just have to do it, to be on the safe side. I do have a
stand-alone magnifying glass with a light. So far I use it only to repair my jewelry.
However, I do appreciate the offer to help

and I will definitely come back to it.
After all, I definitely do intend to use up the 4 liters of 36 mg nic base that I have in the freezer.

I just wish there was another way
Gosh, if I had to repair my own car, I'd still be riding the bus
And actually, the fact that the ANTZ and their Pharma-paid lies are doing this to us, that has ...... me off for a long time. Ever since the Tobacco Products Directive was passed in the EU. The choices will be, simply : 1. do this stuff, 2. go back to smoking, 3. quit everything and start popping Big Pharma pills. (Nicotine does something for some people, you know.) And knowing me, when I cannot vape at all without bothering with this stuff every flipping time - when I now just change the atomizer head on my EVOD or Vivi Nova - I will get a pack of cigs to tide me over. And then - who knows?

I know that this is precisely their intention. But being stubborn can only go so far....
Getting back to topic: No, not every vaper wants to get into the finer points. And it may frighten off / intimidate new vapers when they get told that they "must" get into things like that. Like Claudia P said above: if that had been the only choice in the beginning, she would have continued to smoke. So would I.
