I want to associate myself with the reviewer, who reported on a maladjusted glass. However, I had paid full price and therefore not really feel like because now himself off to fumble around and afterwards to stay might sit on my bad buy. My glass also squinted, the picture the left eyepiece was considerably higher and further to the left than the right, and the images were therefore not superimposed, so one could see two images. Furthermore, no product description / manual was there and also contain no warranty card, quality control slip or the like. This was very disappointing. Had always 1a goods from Amazon get. I hope this was an exception. I sent back the glass and got my money back promptly. Now I will order it again and hope to get an unused, undamaged glass.
