I have found I prefer Kanger's clearos over the others. I really want to buy this but I want it to be in stainless steel not chrome over brass. As to the fixed mouthpiece, I like the aluminum one on the T2, though I'd prefer if it were steel ideally too. The tip alone makes, for me, an improvement over the T3's plastic only tip. Would really like to see a version of this, in steel, but also with T2-style heads as opposed to the T3 style heads here. Never get dry hits on T2s if you fluff your wicks up before use and as I've used them I've thought how nice it would be to have a tank with decent capacity, borosilicate, that I could drop these replaceable T2 heads into. That they're now selling direct to the consumer at what seems to be better than retail, though not quite wholesale pricing, is very very good news for me.
