@seanol that totally sucks, sorry man
I would not buy either the Kangxin or the Waidea any more. I would buy the SXK as you already have. Focal have been promising to stock them any day now for the last week, but I think they are waiting on stock from SXK themselves. I will ask my SXK contact when I next speak to him.
Doris @ Focal is possibly reserving one for me as and when they do get them in, so if she contacts me when they arrive I will let her know to give mine to you. PM me your email address so I can set that up at the time. I'm not in a rush to get a second for the time being, until the resistance issues are fixed - although now I have started doing real temperature testing I am no longer exactly sure if there
is a resistance issue, at least in terms of TC calculations. Will post findings on that later when I'm sure.
Anyway, hopefully it won't too much longer before focal have them. If you're really desperate VaporBreak.com have the 40W, or did last time I checked - they said they could source the 60w with 2-3 days notice but I'd assume they'd be kept waiting right now as well, as the bottleneck seems to be at SXK's end.
You have a Zero too, right? I suppose if you really felt like doing the work (and have experience in such stuff), you could swap the board/screen from the Zero to the Flask. You'd still only have one working unit but at least it'd be the dual battery one with screen-on-top.
