Helpful Positive Review Great Binoculars by TiogaCB, December 21, 2021
Vortex are quality products. I had a pair of Nikon semi-compact binocs and had nothing but trouble with them. Replaced Nikon with Vortex and not looking back! These are great clarity, not too bulky and 10 power to give great up-close looks.
