I have joined here in a quest for knowledge in the world of vaping. I have a vamo v5 and a protank 3 and am liking this combo so far. I am using it with a single 18350 to keep the size down and it seems to work fine this way. I am in search of a new tank and welcome all help. The protank 3 is great and I could always settle on another one I guess but I'd like to have two and i would like try another one. Thanks for any and all help!
