Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
Product itself hold great value. However the services from Zuri are terrible. There tracking and customer reach out needs improvement. It took them almost 3 months to deliver product to my house. During this time I have almost 45 email exchange about the status inquiries. I like product but rate customer service to one star. Hope the will take some consideration on accountability in there service.
