General Warranty: The William Joseph warranty is as straight forward as it gets. We don't care if you bought it at a garage sale, whether or not you have a receipt, if you backed over it with your car, or your dog chewed it up. As long as it remains repairable we will fix it for free, no questions asked.
If our product does not far exceed your expectations at every level, we will give you your money back. Let's face it, if you are annoyed it is for a reason and regardless of what that is, if we don't make it right we lose.
We don't do this so you will never have to buy another product, (that would be dumb) quite frankly it is just the opposite. When you have absolute confidence that whatever you buy from us will bring you more pleasure than the cash you handed over, you will buy more and more Willy J, and then we all win.
