Built my FIRST EVER Vcore coil last night and put it into the eXpromizer. Re-wicked the eXpromizer on Sunday with CC, and last night around midnight, the CC was still clean! I've put probably 30ml of unflavoured 90%VG juice through it since Sunday. It was working fine and tasting fine, curiosity got the better of me, and I also wanted to try a vcore.
So being my first vertical coil, I had no idea what I was doing. I took a piece of CC and wrapped it pretty tight around the coil twice. Then took a small piece and layed it over the top leg of the wire. Screwed on the chimney cap and it's pretty well full of CC in there. Buttoned it all up and it's working awesome! The density of the vapour is even better now! WOW! It just keeps getting better!
