I have a Volt and also a Volcano Inferno (510). I have found that I prefer vaping on my Volt. Funny cause I thought the Inferno would be my fav. I do like my Inferno with the tank much better than with cartos but I am always grabbing that Volt. I love the size and smooth draw on it. I have 2 batts and I have never drained one yet. Just thought I would share.
