Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
They are junky. The left eye wont focus and the images are blurry. When I took them off after wearing them for about 30 seconds, I was very dizzy and could not see straight.
