At $28.48 for a 200mm adjustable wrench they had better be super-douper quality! Like build by monks with Zircon encrusted machinery or something really rare and wonderful. But even if that were true [which it obviously isn't], and I was given one as a gift, I still couldn't bring myself to put it in one of my boxes. Maybe behind the seat of the pick-up. I'd open myself up to a lot of jazz when some one asked me for a 8 inch adjustable wrench. I'd have to say "Sorry, all I have is a Lobster that is 200mm so it is truly only a 7.8740157 inches, not a good honest American 8 inches".
If these jerks wish to copy a successful American wrench design the damned least they could do is leave off the insipid millimeter BS.
