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.
This is completely bogus product. It is not able to withstand nominal pressure. I have use this product just for once and second time its get broken from bottom. Very poor quality product. Not recommended to any one. Not eligible for single start as well. As per Amazon policy return date was on 17th and today is 21 so all my money went in dustbin for such poor quality product.
