When I surf around the web checking out different e-cig site, one thing I have noticed is anyplace that has information about the E9 makes no mention of the 510 and vise versa places that feature the 510 make no mention of the E9 style. It seems that they are in direct competition with eachother. Is there a flaw with the E9 that makes it so unpopular with this forum that I am unaware of? I know there seems to be allot more supplies and things for the 510. Is it simply popularity, has anyone tried the E9 and 510 to find the 510 is a better product?
Just curious
