Hello guys, i'm new around here. I started vaping today and bought the eGo AIO (entrance device for trying the whole thing). I saw lots of videos on YouTube about changing juice, how to fill it properly and stuff. In the beggining, I thought it was amazing. I was getting a good smoke and good taste. But then, out of the blue, I started feeling burn taste, and i didn't vape even for 10 minutes. I tried to clean the thing and refill it, but dind't work. Sometimes when I open it and try something, it starts working until I vape for the 7 time. After that, I get the burn taste. What could it be? I need help, please. TL;DR: getting burn taste out of the blue with a coil used 20 times. Edit1: noticed that when the tank is FULLY completed it takes longer to get the burn taste.
