Best binos I have ever had. Cannot agree with the other review...perhaps he had the dioptic adjusted incorrectly They are heavier than previous binos I have had but the build quality is really very good. They feel like they will last a lifetime

I have been using an old pair of Nikon 7 x 21s for years. My fellow birders got second loans on their homes and bought Leica, Zeiss and Swarovski binoculars. At about 2K or more each they're a little too rich for my blood.
