Review on 🔭 Eyeskey Professional 10x42 Waterproof Binoculars - Perfect for Travel, Hunting, Sports Games, and Outdoor Activities - Exceptionally Clear and Bright Optics by Jeremy Byard

I bought Eyeskey 10x42 Professional Waterproof Binoculars because I needed something that could magnify a bit more than my 8x binoculars and was small enough for a backpack. Eyeskey can be done well, but I couldn't get a field of view that combines the view from the right and left components well. The focus adjustment knob was quite tight and not smooth in its adjustment. By the time I set it, every bird I looked at was gone. There was also a small circle in the field of view that made the image look odd. This was most evident when looking at the branches with the sky behind. I'm about to get my money back. These 10x42 binoculars may be more suitable for those who don't wear glasses or have eyes that are further apart than me or who are younger than me. I may have been spoiled by binoculars with large enough lenses. I bought pairs of 8x56 and 15x70 for astronomy many years ago.
