Yeah... I figured this much - so what makes me think that these "ceramic" coil heads wont do the same thing? Just think - hot ceramic exploding in a closed environment. If you think a piece of hot ceramic shooting out of the side of the RDA is bad, what's to say bouncing around in the coil head body and shattering into tiny pieces is going to make it better? LOL~ oh some of the stuff these companies come up with sometimes.
And this is why we get so much negative publicity.
