Hey! I'm not allowed to post to the regular forum yet, so I'll post my question here instead. I have the iTaste MVP which came with two iClear 16's. I bought a couple additional heads, and now I'm looking at other clearomizers.. specifically the Vision Ego and Vivi Nova's. First.. since there's approximately 8 million different clearomizers.. what's currently accepted as being "the best" (I realize this has a lot to do with personal opinion, but...) Second.. the iClear 16 and Vision Ego look almost identical.. are they? and if not, do they by chance share the same atomizer heads? And.. any compatibility with the Vivi Nova's? Thanks!
