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.
Beware fake products. Seller "Key savings" is selling really bad fake replicas. They are shaped slightly differently, sewn differently, and smell like old tires. They are probably toxic and should not be on your body. My original ones do not have these problems.
