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.
Good quality optics but let down by a flimsy focus adjuster which dents easily and an eye cup that falls off. It’s happened to mine and two other friends pairs so it not a one off. Another bad point is a twig got caught in the diopter adjuster as I brushed past it, small piece remained after removing it and now it no long moves freely. On the positive side though, image quality is great, the form factor is nice and compact and they are pretty light.
