ok, only two issues with my set up. first, its a juice HOG. I killed a full 2.5ml tank last night in under 2 hours. Second, there's no easy way to refill this bad boy. With the ss mesh I was told you simply insert the needle through the straw hole, but theres no such hole in the cotton wick. In my attempt to wedge the needle between the wick and sidewall of the wick hole I totally mashed the wick and coil and now I'm back to square one.
So to re-fill the Def-con you insert a needle into your wick? isn't there another hole to alleviate negative pressure or does it just rely on a hole through the center "straw wick"?...odd...I think I'd be drilling another 1 mm hole in the base your wick/terminals come out of. Anyway, props Hildi, glad you got it going on and you're happy...another 2 - 3 attempts and it'll be "old hat" to you and you'll nail the sweet spot every time![]()
Sorry, but since I got a Genesis mod I've never looked back into vaping with Silica/ Fiber glass wicks on a rebuildable. Oxidized SS Mesh is currently the best wicking material there will be for rebuildables!

Try wrapping a single layer of mesh around the lower portion of the wick leaving enough bare cotton at the top to wrap the coil on. This should ggive you enough ridgidity to make the wick much easier to insert/remove.

Your talking about the DefCon, right? if not stop reading here... There are 2 tiny holes in the silicone cap, off to either side. The same cap that has the hole for the wick. Those 2 tiny holes are needle holes from which that silicone cap was originally intended for use. The cap is repurposed for use in the DC. So, if you take a sharp needle you can very easily enter the tank thru one of those holes. Just be sure not to push the cap down or you will have a disaster on your hands. I have not tried this, but I have owned and used the original product that those silicone caps come from, and that is the only way to fill the original product, thru those 2 tiny holes. Again, I have not tried this, attempt at your own risk. I would not tell you this if I didn't think it would work. I def would not try it w a blunt tip needle you will for sure push the cap down. Good luck.ok, only two issues with my set up. first, its a juice HOG. I killed a full 2.5ml tank last night in under 2 hours. Second, there's no easy way to refill this bad boy.
