I was just reading a thread about Smok mods and the problems they have. Then I thought, I don't think I've ever seen a complaint about the Battlestars or Charons. I'm going on 6 months with two BS which I use everyday. Not a single problem. I've got a bit of chipping going on where the tanks sit, so I can't see it anyway. Damn things are great...I need a couple more.
