My Aspire Atlantis 2 seems to be using up a crazy amount of coils. I love the tank, but I'm just going through a ton of coils--.3's, .5's, TI's, even Atom coils. I've been trying to rebuild some, but having a tough time getting them right. I suppose more practice is what I need to get the rebuilds to work. In the meantime, the coils just don't seem to last at all--nothing like my other tanks. Anyone else have this problem?
