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.
My husband is delighted with his Dacasso leather coaster. He spends his afternoons teaching classes online and needs to keep a glass of water with him. The coaster matches his other desk things (also Dacasso) and appeals to his sense of aesthetics. Our three-year-old granddaughter likes it too, and often tries to take it for herself.
