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.
Hooks are smaller than I expected - a regular bungee cord will not fit. Each individual hook comes in two well designed pieces; a metal shaft that in screwed into what ever will hold it, and the black double hook that then screws onto the shaft. If you want to remove it, the black hook screws off the shaft, and the metal shaft remains where is was installed. It may require drilling to remove shaft. Other than that, hooks are well designed and appear quite sturdy. Have not yet installed mine.
