hey all, i am still getting used to all this stuff... i have been cig free for almost eight months and it seems like its been nothing but struggles to find something consistent for me. i finally feel like the new vivi nova 2.5 is pretty legit and ive been using a couple minis to get me through. but i hate having to refill them so much!!! i purchased a regular sized one and it is very tight draw and way to harsh! at first i thought it could be a bad head (i like good head haha) but that wasnt the case because i put the same ones on my minis and they work fine! did i get a bad tank or what? any tips or tricks to get this thing going? thanks!
