I'm a new member here, but I've been lurking around for quite some time doing some research on e-cigs. I purchased a Volcano E-cig for myself and my wife about a month ago. It's not a bad product, but we weren't totally satisfied with it (battery life, cartridge life etc...). So, I just ordered the 510 from Cignot.com. Hopefully it works out better for us. Anyway, I just thought this would be a good place for my first post. Thanks for all the great information on this board.
