I certainly didn't intend to infer anything negative about Phiniac or their products. I've both purchased their products and promoted them to others. I've just never heard of a juice so potent that it can't be held by a metal cartomizer. (Of course, that doesn't mean it isn't possible. I'm sure that I have plenty to learn about vaping.)
If the orings were in place, is it possible the center tube of the cart was pierced? I know I've done it before when punching carts, resulting in gurgling and juice running out of the bottom of my tank. It doesn't take much. I've taken them apart and you can't even see the hole, just that the fabric is looser in one place.
Even if you had to meant to say we might have forgotten the o-rings it would not have been the worse thing you could say. We have actually done it once or twice. We have gotten better at packaging, but who knows... we are only human. So no insult taken here!
