The Serpent Mini is my first RTA and so far I'm really liking it and it's working well. I did have one question. I had noticed that when I top off the tank, I start to get noticeably more vapor. I thought it was from the additional juice, but then I figured out that it did the same thing from just removing the top and replacing it. So it obviously has something to do with the pressure in the tank. Is this normal or is there something I should be doing differently? I'm running a 3mm, 6 warp, 26 ga SS316L, 0.46 ohm coil with a cotton wick, at 480F. It's working great and I'm getting good vapor, it's just that the vapor dies down slightly after I vape for a bit.
I keep the top on my Serpent Mini loosened about 1/8 turn from tightened down. It works best for me this way. Never have leaks and always vapes like a champ. I love this RTA.
