When Dr. Neil English, author of a book about the history of visual astronomy, published a very positive review under the ominous title “The Remarkable Svbony 10×42 ED” (, we were intrigued. After all, the binocular in question is a low price China-made private label binocular which you would not expect to get any special attention. But when BINOCULARS TODAY ordered a sample and inspected it, we had to admit that at a price of roughly 150$ equivalent, the Svbony 202 10×42 ED is indeed a remarkable instrument. We do not know any other 10×42 roof prism binocular in this low price market category that matches the performance to the Svbony. Reception in the market has overall been positive so far; however, some complaints in internet forums and the encounter of a faulty sample by BINOCULARS TODAY (blocked diopter adjustment ring) seem to indicate that quality control, still a weak point also for many other binoculars made in China, is an issue to improve for Svbony.
