To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I don't have anything to compare them with but they work well. A little bit of purple fringing on distant thin objects but otherwise pretty good. I had a problem with other binoculars because I wear glasses but these work fine. I would recommend them for the price.
My only real issue with these is that the caps for the eye-pieces aren’t flip-up. So when you take them off you have to be careful not to drop them or lose them. Focus is smooth. Eye relief is good. Sharpness is really good for the money. Color is a little flat but hardly noticeable after a while.
