I've been using the Vicious Ant Goliath for a couple months now and I have run into many problems throughout that course. It's always this terrible metallic taste that usually leads to one of the coils snapping. It's very frustrating to live in fear of it happening. I try moving the coils further from the top cap but that doesn't seem to be working very well. I love this rda but it's expensive and a hassle. Help me figure out wtf is going on with it.
