I've tried a couple different things on my twists. The iClear 16 tastes and produces the best over a CE4 clearomizer (I'm still trying to figure out Stardust and CE3, 4, 5 blah blah. They all look the same to me!) I've tried the Kanger MT3 too and it seemed great at first, but now after returning to it after the iClear 16, it tastes like garbage. On a fresh atty (dry burned or not) it still tastes awful. But held a lot of liquid and people seem to really enjoy them. Not me. Full size Vivi Nova is on the way which may be too big on the twist, but I'll give it a shot.
