Hi! I'm new to vaping and am using my first set of cartomizers. I've been using several in rotation with different flavors so i don't know how long each has been used but I can say roughly around 2 days. In the beginning the vapor was easy to inhale but now I have to suck on my drip tip with a lot of force to get vapor out of it. Do you know why this is and if there is a remedy? i would appreciate your advice! Have a good day!
