Mine doesn't pool overnight (well it does) but it pools over a matter of minutes. As in, every single time I drip into it and take a couple of vapes, juice starts seeping (not droplets) from the space in between my atty and mod. It's almost as if there was a ring shaped cut all the way through the atomizer base and juice just leaks directly out; it makes no sense to me. I replaced the O-rings with the spares as well, carefully, and the issue remains. I thought at one point that it may be that my coils were placed too high resulting in a lot of juice popping and in return resulting in a lot of juice flowing down the inner top cap edges. Even though every build I see everyone else do is right in the middle of the posts (vertically), I dropped my build down to level with the bottom post holes just about 1-2 mm above the airhole tubes. Still leaks freely as ever. And just to repeat, there is NO juice coming from out of the airholes themselves, it's all coming out from between the top cap and deck. I really don't understand how this could only be happening to me, but I do hope that I got the one bad one where they made the top cap or deck just a little off, because I really do love the vape off of this thing. I was especially pissed when I went to my Hcigar VT200 to find it sitting in a pool of juice that had penetrated through the multiple vent holes in the bottom of course... Anyway, I contacted the vendor, who didn't reply to my email except with a "Shipping confirmation of return or special order" and since it has a tracking number I assume it's a replacement. What do you guys think? They wouldn't send me a return envelope...would they?
