I have Evic, Vamo, and an Itaste VV for my VV batts. And in order id say Evic, Itaste, Vamo. I am a huge fan of the Evic, made of aluminum so its super lightweight (crazy light with an ego upgrade 18350 tube and evod!), provides a nice smooth vape, and has tons of options as far as how your vape is delivered. I like to mess with mine and have it fire at 8W when i press the button so it gets going quick, and backs off to 6.4W so i can take a big long drag and not worry about burning my wick. What other mod does that? If youre looking to be dirt cheap though, the Itaste VV (and the MVP for immense battery life) is lightweight as well and provides plenty of power and a great vape.
