I've been thinking about going from my ego twist clone to an innokin iTaste VV. They look pretty slick and the variable wattage feature looks enticing. Although the 1100mah of my ego may have spoiled me and pretty much lasts me all day, I vape it pretty heavily. I somehow doubt the 800mah of the iTaste VV would keep up, maybe buy two? I wouldn't really want to have to drag a second one around though. Anybody use one? Thoughts?
