Have to disagree, I've managed 75 russian squeeze bottle drops into a veritas , turned it horizontal on the air hole and not had it leak.
Here's a vid I made a few months ago for a friend who wanted to purchase the authentic, this is about 65 drops on a horizontal, but on a vertical you can cram 10 more drops
In a veritas you can have standing juice and no chance of it leaking cuz it goes up the side channels. In a darang standing juice will happily travel up the channel and leak out. If you turned either upside down prepare for a shower, but that's any rda
Ok .. maybe my coil is a little closer to the air hole and make a "juice bridge" i will look at that
