I ordered a bunch of premium cartos from V4L last week and they all(more than 1/2) seem to be duds. They spit and sputter off and on creating no vapor and then it taste like burnt plastic. I took the end cap off and saw that they have a barrel shaped (plastic?) thing that looks like it should be down inside holding the atomizer in or straight. Well these cartos have that plastic barrel shaped thing at the top of the atomizer where it curves and I think that is what is burning giving me the burnt plastic taste. I don't know if I should return all of these? Or is there an easy fix? I am sick about it because 1. I wasted alot of juice trying to get 1 that works and 2. I got these to try some flavors with and now they have my Salem menthol in them. Not sure if I should return or something that is easy to fix. As always, any input is appreciated.
