I purchased these binoculars without ever looking through ANY Athlon optics ever before. With that being said I was skeptical about the purchase and only had reviews based off a buddy of mine and what I found online. But let me tell you, these things are absolutely 100% awesome binoculars! I haven't been this pleased with a purchase in a very long time. I like them so much I turned around and purchased two of their scopes. I'm a huge fan now!
