I still have my working atomizers from last October. I chain vape everyday and rotate a few atomizers. Some of the cartomizers I tried out were just "ok" and the flavors didn't come through for me as much, or as consistently - or weren't wicking fast enough using 3.7v. LOL that said, my best vaping right now is coming from a modified RS CE2 R4 cartomizer, where I clipped the wick out and added Pyramid Tea Bag (PTB) material as the wicking medium. Look up the PTB mods.
If you read around here, and fully understand the internals of both attys and cartomizers, the insight will allow you to almost never destroy either.
In either case, keep them wet.
Good Luck!!
