These binos are legit. I've got 2 years on them now and haven't looked back. I almost feel bad leaving my trusty old Swarovski 15's at camp but really there is no need to pack two pairs of binos anymore. Clarity and light are as good as it gets to me personally. I have swapped back and forth from the el's and the nl pures and I like my GPO better. Not much else to say.
