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.
It's ok ok type of product. Don't know how long will it last. Just serves the purpose but not happy with build quality and finishing. The brown cloth used for this product looks as if it was an old piece of cloth...nothing in it that makes it look like a quality and new product. Shouldn't cost more than 200 rupees!
