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.
Product is unstable and made out of poor quality plastic. It is extremely overpriced. I accidentally bought this, only to find that the same was available on another site at half the price. The finishing is very bad and one look at the actual product I know it wont last long if the least bit of sunlight falls on it.
