Now that I've used the Shotgun mod for over two months, my button has broken in nicely. It's still a stiff button, but that will never change with the magnet. I've cleaned my contacts every few days, usually when I re-wick. The silver plating on the copper is SOLID! All in all, I can't be happier with this mod. I think the button has actually strengthened my pinky finger! When I first bought it, I had to use my ring finger to fire the mod after a couple hits since my pinky got tired ;p Nowadays, it's a pinky throw all the way.
