Bests & Worsts Reviews from Amazon

I needed a replacement for my 30-year old Nikon 10x25 binocular which always gave a flawless image until somehow it went out of alignment. This is my second purchase, the first was a 12x42 roof prism model which was a disappointment because its optics were inferior to the Nikon. I worried that there might be nothing as good as the Nikon at a moderate price. My eyes aren’t as good as they were 30 years ago, but I can now say that the Occer is a nearly perfect replacement for the Nikon. The image is razor sharp and the focus wheel is light. I feel no eyestrain, which indicates that collimation and alignment are correct. Just ignore the claim of low-light night vision, none of these binoculars work well in low light. This binocular uses the conventional porro prism (offset) design, as opposed to the roof prism designs used in the straight-line models. Wikipedia has an excellent article on binoculars in which the two prism designs are explained in detail. My recommendation is to avoid low-priced roof prism binoculars; the article describes the compromises and complexities of the roof prism which may account for some of the flaws in my first purchase. The body of the Occer is plastic but feels solid and well made. I am only guessing at the durability rating, but with care it should outlast me. I didn’t really expect to get a binocular of this quality at such a good price.
