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.
These are very nice and worth the money. I gave only 4 stars though as one of the items in package was bent. So a bit of quality control may be needed at the factory. My issue was I needed exactly that many so I have one closet door with a funky spring.
