Either Swarovski, or Zeiss, owns Khales. So they are very good quality. They are just a little less expensive than the parent company's products. I've never owned any of these three brands! They just have always been too rich for my blood!
But the Zeiss Conquest is comparably priced to the Leupold Vari-X-III, so the next time I'm in the market for a scope I will take a look at them.
