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.
Very good product. I have used it to store blankets, quilts, bedsheets n our winter clothes inside our bed. One thing that is too good is that its very big in size n is spacious. Material alsogood. Worth the price.
