I love mine. It has been rock solid for me while a dozen other mods have died or flamed out. But who knows, I just had two IStick 20's go bad on my wife and I in the past week, and I thought they were pretty solid, too. One of them just decided to fire the atomizer endlessly, and I barely got it off the mod before the entire rig got too hot to touch. Sobers one up, or maybe makes one drink, depending on dependencies.
