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.
I thank Amazon for providing a genuine item. Only one thing I request from the company that, packing of glass bottles should be perfect, but anyhow without damage I received the item. Need improvement in packing,,,,
