I have owned various brands of optics over the years and have found these to be among some of the best. They are quite clear and easy to focus , even in very cold weather.They are very durable in all weather conditions and have excellent clarity.The only salient issue I have with them is that in warm conditions they have a strong tendancy to fog the rear ootic from body vapor. Normally I would not mention this, but it is much more prevalant in this optic than in previous binoculars of similar quality thatI have owned.I would recomend as a medium priced optic that is very durable under all conditions.
