Thanks, Doug.
Looks to me like Leupold, Zeiss, maybe others could be a bit more aggressive in stopping these Chinese knock offs from using their brand, maybe taking action against outlets like EBay who seem to play along with the deception. They usually do reveal country of origin, but have the Zeiss or Leupold logo on the product. IMO, that's shouldn't be tolerated.
OTOH, a buyer would have to be pretty dumb to buy a knock off "Zeiss" at half price or less with China as the country of origin...
