My main problem I have with the Atlantis currently is the stock coils. I have only used 2 so far but both have been harsh as can be for the first hour or so, then they smooth out a bit. I heard this is to do with the wicking material they use, so later I think ill pull one apart and put all organic cotton in there and try it out. Also the first coil I had the inner cotton core on the coil came unbound and blocked off the air flow, so I have to try and fix that one as well. Other than that, great draw on it, big clouds, good flavor.
