blu is because that's what everyone knows....it was media frenzied....plus most people just seem to think that vaping is too difficult so they just keep buying disposables instead of kits (i work in a gas station, i try to educate when and where i can but 90% of the time, they just want to supplement their smoking habits or just don't believe that the non-cig-a-likes could actually help them stop smoking, or feel that they'd just look stupid vaping on them.....because you don't look stupid with that cig in your mouth)
