Let me tell you that I have been very happy with these binoculars. First pair was out of line, but replaced in an instant. I had hours of enjoyment . Plastic brace for tripod is somewhat useless and you need to buy a solid steel brace for a tripod . And you need a tripod... if you hold them for more than a few minutes because they are heavy to hold for extended periods of time. I was extremely disappointed when they dropped from a 1 meter high shelf as they were knocked completely out of line and couldn't be adjusted with the screws. I would buy them again as they were a lot of fun for the price. That extra magnification ( 15x 70 ) gives some of those star clusters the Wow factor.
