Which model Vortex did you get? I've read that the Viper line is on par with the VX-III, and the Diamondback line is on par with the VX-II. The Crossfire, is their only Chinese made scope, but they get pretty good reviews for a cheap scope. Vortex seems to be taking the scope market by storm. They are producing great products, at great costs, and offering great customer service that's as good or better than Leupolds. I've not read much about these scopes on this site, but if you look around on other sites, there is a ton of info on them.
