I too just don't like cartomizers. I've tired, several different kinds, with tanks, without tanks, 2 holes, slots, DCT, single coil, ranges of ohms from 1.8ish to 2.8ish, in every voltage range my ego twist offers. I just can not get the same flavor out of them as I can out of a clearo, and there is always a background muted chemical/plastic hint to every vape. I try them again every so often, I just put a tank together last weekend, as I was thinking I might like a Phiniac tank for my citrus juices, but I just can't find the sweet spot for vaping them. That's not to say I won't keep trying now and again, just that my ADVs are in Kanger T3s and Vision mini Novas.
I've pretty much decided that it's much the same as juice flavors. Two people can vape the exact same thing, and get two totally different experiences. Such is life.
Congrats on 3 weeks!
