Off brand optics can be quite good optically, but not a bargain in the long run regardless of price or country of origin. If you're using binoculars primarily for casual viewing at concerts and sporting events, where the chance of getting home without them is high, it may not make much difference what you buy. However, if you plan on long term daily use and/or in harsh conditions, go with a brand with a proven track record of good customer service. Optical quality doesn't mean anything if the company isn't around if repair is needed. Off brand optics should be considered "disposable". I would not pay $300.00 to $600.00 for "off brand" binoculars, especially since there are so many good "name brand" models at that price point.
