i do not agree. the vortex failed 3 times 3 were returned. the eye piece is horrible on the vortex. who ever assembled the 3 i purchased did not care. one even had a piece of foreign material in it and one had spotty coating on the inside that was pronounced through the image. one had a medal grind noise as you used eye piece to magnify. thats wrong........... customer service stated some do that, either live with it or return it. (BS) talk about make your head spin when looking at distance. i will never buy any vortex optic again. the ol 3 strikes your out.......... swarovski is old world craftmanship. you pay for what you get. in vortex i got a pain in the arss and massive let down. to buy one not once but 3 times (razor hd 20-60x85) and have these problems was a punch to the face.
