What is the difference in the e-liquids? I have yet to try any of them from here, but I have heard good thing and I'm eager to try some of the flavors. I'm just a little bit confused as to the difference between Premium Nobacco, Wow Vapor, and Nobacco Juice USA. The site says Wow Vapor has maximum vapor and taste but Premium Nobacco is more expensive? Any insight would be very helpful to this newbie.
