I have been vaping about a week. I had 2 pvs that I bought at a local smoke shop and the Pilot. They were "OK" i guess. I got my eGo in the mail yesterday. For the first hour it was awesome - lots of vapor, clean tasting, enjoyable. After that things starting changing. I started getting a plasticy taste and hot vapor. I kept the cart full of liquid and even a drop or 2 on the atty to make sure it was nice and wet. By last nite my throat was irritated and I was coughing. WTH? I am wondering if there is anyway to get a metal cart instead of this plastic. The idea of inhaling burned plastic does not appeal to me obviously for health reasons. Anyone got any ideas what the prob is or about a metal cart? Thanks!
