So I have been vaping on my ipv2 and tanks for a while, atlantis now, but I am wanting to get into rebuildables and bought an rda, wick, wire. But do I need to get a meter if I am using it with an ipv2 still? If so what is a good one to buy, most I look at on amazon do not have the greatest reviews. I see a tobeco one on amazon for $15, would that be okay?
