I just ordered the 30mm, well unless something happened when I pressed the button to order it, I happened to actually get the 25mm. Just got it yesterday! The day after I purchased I saw the email notification that I had ordered a 25mm, so of course I sent message to eciggity, but of course I got no response. But anyway, still a nice tank, however after putting in some fresh claptons. All I'm getting is a metallic taste with a smidge of flavor from my juice can't understand what's going on there. I've been building for a while figured it may be touching the deck cap, so I went from 3mm to 2mm wrap. Still same metallic flavor. I don't know if it's the deck itself or what but I hate that I can't enjoy my vape! But I also ordered a griffin from another site so I guess I'll just have to see if it's my building or the actual VCMT messing me over... But build quality seems to be legit. Cloud is fierce. Just can't get rid of this dag'on metallic taste. Think I'll just soak it in alcohol and see if the terrible taste persists.
