wow. Full year? My coils rarely stay in the RDA over a week. Not because they are bad or anything, but I just rip them out and rebuild them. One thing I liked about my cigars and pipes was the build up. Loading the perfect bowl. toasting it with a match and getting the false light. letting it sit a min and then truly lighting it and tending it so that I get the perfect burn all the way down. Or trimming the tip of a cigar, lighting a ceder splint and slowly toasting the foot before finally lighting it and enjoying the smoke. With my vaping as was already stated, wire is pretty cheap. I tend to only rewick a set of coils once before Im pulling them out and rebuilding something different.
