Review on 🔭 VANGUARD Endeavor ED IV 10x42 Binocular: Premium Hoya ED Glass, SK-15 Prisms, Waterproof/Fogproof - Ultimate Optics for Outdoor Enthusiasts by Doug Knight

I got these (10x42) and tested them between my Steiner 8x42, Nikon Monarch 8x42 and Vortex Viper HD 10x50. Image quality was worse than all three binoculars, even though the Nikon is significantly cheaper. What frustrated me the most about the Vanguard was that the focus knob was extremely sticky/twitchy, to the point where it was almost impossible to focus accurately when looking through the binoculars. In my experience, they are junk and inferior to much cheaper binoculars.
