Hey guys, I'm new to the ecig forum and was wondering what you guys thought about a couple different companies. I want to get something small to carry around in public. I've done a lot of research on all of the different manufacturers and as many of you already know, there are way too many choices out there. So, I wanted to ask you veterans what you thought about the Volt, Volcano, V2 and the Apollo? I know these aren't mega vapor producers but will any of these get the job done for something very slim and inconspicuous? If you guys have other suggestions, I would love to hear them! Thank you in advance!
