In the past eight months that I've used EMDCCs I've only had two or three faulty ones. This morning I filled a new clear one with Alien Visions' Pineapple Pulp, started vaping, and immediately noticed cracks in two spots going the entire circumference of the cartomizer. I tossed it and began filling an old one that I had cleaned and about 20 drops in I noticed cracking at the top of the cartomizer that wasn't there before. I'm thinking it's the juice, but has anyone else ever experienced such a large amount of cracking after filling with a particular juice? Very strange.
