I love mine, and RCBS warranty can't be beat. I've never needed warranty over my rockchucker, I don't know how you could break one, but I have over other RCBS stuff I have broken, even when it's been due to my stupidity and I've told them that they still send new parts for free. Tough to beat that.
I should qualify that, I guess I do know how you can break one, I was on the phone with a very nice lady at RCBS one day and mentioned that it was awful nice of them to warranty stuff I broke that wasn't their fault. She said one day there was a crowd around a work bench so she went to see it. There was a rockchucker broke in half, I guess some guy had attached a 3 or 4foot T handle and was trying to swage bullets, she said he wasn't getting warranty.
