So last week I got two brand new standard resistance 510 attys from alien visions. I used one the day I got it, and it works like a champ. The other I just tried, and it's giving me this strange, almost metallic taste. I know what a burnt atty tastes like, and it's not this. And neither came with primer. The taste is harsh, maybe chemicalish? I don't know how to describe it and it feels like something I should not be inhaling. Any ideas? Or am I just freaking out?
