The only problem with Vortex is some of their optics are made in China. Such as the Diamondback bino's. And yes, I do own some and I'm somewhat ashamed to admit that I do own some. Although my excuse is I thought they were made in Japan when I bought them. Couldn't pass up the deal- $120 for 10x42's. But man I really hate supporting companies that make their products made in China.
