My killer is a week or so out but I'm trying to get things ready.
adeline, are you still running cotton in yours instead of silica? If so, how is it holding up?
Also, I wanted to add... Since my initial recoil/rewick (8 days ago), I've been running the same cotton. It's a cotton yarn. I have the ends of the yarn dipping below the cup into the sera wool. Feeds very nicely. I only recently (last night) started seeing dark liquid seep into my tank, so I know it's time to rewick.
I'll pull out the cotton, dry burn, either replace my puff of sera wool or just rinse and reuse. That's the great thing about Sera .. aside from the fact that it's dirt cheap. I ordered a TON of it, not knowing how big the packages were. I have more sera than 10 people could probably use in a lifetime. Then I'll just put a new piece of cotton yarn or something through the coil and vape on!
The Killer has been my main rba since the recoil ... including 2 vape meets, and pretty much constant chain vaping for at least 8hrs/day. I'd say the cotton held up pretty well.
