Great value, bright and sharp images. I especially like the long zoom range (8x-16X) in a compact package. I would recommend this product to anyone wanting a flexible binocular in this price range.

These are the next step up from the 8x close focus(18") set I purchased previously. I wanted a little more magnification and these extend it to from 8x to 16x. Very good for Florida bird watching from the lanai. They are a great set of binoculars at a fair price.
