I don't hunt as much as some here, but I've really used mine hard the past two months in wet and cold conditions, as well as dirt blowing, sandy, arid conditions on our mule deer hunts. They are holding up well and continue to provide a fantastic view. My only gripe is with the cheesy lens covers, which are too loose to stay on very good. Our mule deer hunting really, really taxes optics because it's so sandy. In fact, my buddy was riding out of one of our hunt areas too fast on his ATV, and banged his EL's on the handlebars, knocking the right barrel out of alignment. It also would not focus anymore. I'm sure Swaro will take care of him. So far so good for me.
