I bought one of the c8's with my last order, but it was the same order with the Phoenix bottom coils, so I didn't really end up giving the c8 much of a shot because I was so impressed by the Phoenix. Well, I had left it sitting for at least a week when I picked it up and decided to give it another whirl (no leaks at ALL) and it tasted great! I have to admit, at first, I thought it was a little bit gimmicky? It just seemed like a lot of hardware for a 2 mL tank, but it looks kind of steampunk and so far it is working great for me. That first tank breaking it in was so-so, but since then, it's been great. It's nice to see something that is not only made to work on an ego, but made to work OPTIMALLY on one. I put this on a vv, and the hottest I even wanted to run it was 3.7V (and even that was a bit too high).
