I asked to have a look ready to laugh at them and feel great about how superior my FL's were and I was absofreakinglutely blown away by the brightness and sharpness. They were just as bright as my 10x42 FL's and probably cost under $100. The trick was the apparent field of view was half the size. They made a great design decision and took all that light they lost with poor coatings and just made the AFOV half the size and got all of their brightness back that way, plus by being porros they had an advantage to begin with. Let me tell you they were very sharp in the center and extremely good edge to edge also. I had my FL 10x42's in my bag and I left them right there because for sure no one was going to get a wow out of them, they were getting just about the same view only with a much smaller circle. I learned my lesson that day just how good even a cheap a porro can be.</blockquote>
