How good or bad the iClear 30 is, is subjective. I prefer the vapor quality and taste from it over all of my single coils clearos. That said, it isn't my favorite dual coil clearo at all, and the one that came with my MVP 2 is currently not being used. I don't like the shape of the drip tip, it isn't glass, and it does use a lot of juice. The rate of juice being used however is comparable to other dual coils. Two coils just equals double the vapor and juice consumption. I prefer cartotanks for superior taste and less juice consumption, and my favorites are tanks from IBTanked and Cirrus so far. Phiniac tanks are also great according to reviews, and I'll be ordering from them next.
