Just a bit ago, I was prepping a new Kanger MT3 for the wife. I've had these for a while, think I got them from Health Cabin, which is neither here nor there. Original Kanger MT3, 5 pack, in the box, in sealed individual factory bags.
Pulled the last 2 out of the box, pulled them out of the bags, tore them down to clean and fill when I noticed something strange on the last one, in the tube.
After taking the pic through a magnifying glass, I pushed the "blockage" out with a toothpick.

It's a curved metal item and plastic ball.
The way they were placed, I could Almost think it was on purpose to restrict air flow, although I'm pretty sure that the placement is too easy to dislodge.
Knowing that my wife still, now and then, vapes straight to the lungs, against my advice, if I hadn't caught this by looking like I normally do, this could have been a serious life or death issue if she vaped them into her lungs.
Always check your items out fully before 1st use, and anytime you rebuild!
