Hello everyone, I've been a cigarette smoker for 10 years and have finally decided that since I will become a father this August, its time to quit. I bought a NexGen starter kit about a year ago at a local smoke shop on a whim, used it for a while, and went back to my old ways. But now I am committed to stick with vaping. I cam across this site looking for an answer, maybe you guys could help. I tried a friend's blu product and absolutely loved the flavor way more than the nexgen cartos I've been using. Now I know I can refill my nexgen cartos with the same fluid the Blu units use, but I am currently out, can I just use a Blu carto on my nexgen battery? They look quite similar... Thanks!
