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.
I exchanged duplicate product which i had received previously. Now after replacement i got new orginal product of fasttrack. It looks so good and satisfied. Amazon replaced within 2 days after i requested.
It is a genuine product. I received it as it has been shown in product details. It was in a sealed packet from the manufacturer. I am very happy to receive this product. Thank you Amazon. Price of the product is almost same as in any authorized showroom.☺☺
