So i just received my first pack of cartomizers in the mail from LiquidXpress today. I've been really excited to try these since I've heard good things about them. I fill up my first one with about 20-25 drops like i heard you're supposed to and vaped it for a little bit. Seemed like it was working really well. I let it sit for a while came back to it and now it has this horrible burnt taste to it. Did I do something wrong? Or is something causing it to taste like this? Or just a bad cartomizer?
I dont wanna waste filling up another one since I have some more juice coming in the mail that i wanna fill them with.
I'm a noob, i know..
