Has anyone used a juice that "melted" or cracked a polycarbon clearomizer? I'm using Smokeless Image X2 batteries and these clearomizers (I believe there's an Ego version of these out there as well). I love the easy filling, they don't leak, and I can vape all day without getting frustrated with carto top offs. My only concern is there are a lot of posts around about clearos being melted or cracked with specific juices. I realize that's just how it is when you put certain flavors in plastic, not really something a juice maker can control. I'd just like to avoid putting a known clearo eater in one. I haven't seen any specific KBV juices on the known "no-no" list, so figured I'd ask here and see if anyone's had one that I should only use in cartos.
