I've been vaping almost a year now, and am still using a variety of "entry level" hardware. I have 2 eGo batteries, an evod battery, a protank 2, protank 2 mini and an evod tank. I'm more than ready to make the jump to a high end battery but don't have much insight into the differences or even where to get them, as all my local stores carry the products I'm already using almost exclusively. I vape juices varying from 15-18mg and prefer tastier tanks that have less throat hit. Any helpful suggestions?
