Amazon calculates a product's star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
1. This product quality is average and not so good, however it is worth for the money. Slightly expensive when compared to quality. 2. Poor installation guide and is definitely not for the normal peoples. The guide is just useless. Spent almost 4.5 hours to fix but still not satisfied with the installation due to gaps here and there. No proper guide for the screws. 3. It is just ok and can try better if you have options.
