ive been rocking my vamo for about a week and am LOVING it. but i was currious as to what batts are the best vape for the buck. i have seen both samsung and panasonic types on different sites but not much difference in the on site reviews. are the noname just as good or should i go for the higher end batts. also was wondering if anyone on here has an xtar WP6 and what they think of it. thanks in advance for your help.
