"I don’t often take the time to give compliments to a vendor but it’s very gratifying to see a quality U.S. made product that works. In my hobby (Ham Radio) of restoring communications equipment... I have to deal with Bristol fasteners and being able to use interchangeable bits instead of Allen wrenches is great." -Craig
