I can almost certainly exclude a defect with my device, oring etc. all seem alright, it's tight when I close the airflow hole and suck. Machining is not "super great" but is ok, can also exclude.
I wouldn't exclude a defect.
I only have the ones with the oval holes and wick mine basically the same as Gatok showed in the pictures, with a little less cotton.
Did a little test this morning, as I was cleaning a few items anyway. Filled one up with the thinnest base liquid I had laying around (80PG/20VG), just to see what would happen. It's been standing for an hour now, and no leaks whatsoever.
It's really hard to make this thing leak.
