I had engaged me over 2 months by purchasing a pair of binoculars. In the beginning I bought used glasses from top brands. (Zeiss, Steiner and Eschenbach). These glasses I have even today. Some of these binoculars were 40 years old. Then I came across the Olympus glass on Amazon. Thought to myself that you can not really do much wrong at this price. The delivery came on time as usual Amazon. The glass was delivered properly packed. The quality of the glass is what As for sharpness, brightness and contrast for the price excellent. Also, I think that one is often claimed for so little money, should get no zoom binoculars, so not true. Comparing to old jars need the Olympus not to shy away from. The quality is equal or better, with the advantage that I now have but a push. These used binoculars were even now still more expensive than the Olympus.
