The binoculars came with a wrong screwed left lens. All objects that are considered to appear twice. The binoculars are going from Olympus, but is manufactured in China. The complaint with Blue River went smoothly. The second unit of the same design was again supplied with wrong eineschraubtem left lens. As a trained East Germans of course I tried to fix the defect itself. Since the screw of the lens in the second case was not so tight, me the repair is successful. Now I have a top pair of binoculars that you can hardly get in the size 10x50 and this quality at a lower price. Large field of vision, no color distortion at the edges of objects, scale for the viewing distance and a relatively low weight. For general use, such as wildlife viewing on the day in the distance up to 300 meters, I can only recommend the binoculars.
