If you're looking for a very inexpensive binocular, the Optisan 7x50 Pro III Binocular is about as good as one can expect something in this pricepoint to be. Surprisingly bright and sharp, that it can do this at the price is just shocking.
NOTE: Though the box makes no mention of the implied warranty coverage, B&H has arranged that for one year after purchase any Optisan binocular can be returned to B&H for immediate replacement if it has suffered from a manufacturing defect.
