"Free" means you leave a theoretically refundable deposit equal to the value of the tester and get it back when the tool is returned. How accurate it might be depends on how badly it was abused by the last guy who used it. I don't know about anybody else, but I'm pretty selective about who uses my hand tools, let alone my precision test equipment.
