I was expecting to pay something for the replacements, but when they received the jaws that I sent back I didn't hear anything from them until the vise arrived at my door. Maybe when they inspected the jaws I sent they found something that caused them to think it was a manufacturers defect. After I received the new jaws I sent them a very nice thank you letter for the replacements!! This happend many moons ago, so maybe things were a little different then.
