To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
The worst product I have ever got from Amazon. First, the product didn't arrived at my address, I have to go and pickup this product and it's too late. Second thing, after assembling everything the coffee table starts shaking meaning not balancing everything properly. I tried two times, even after it's still shaking.
