Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
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 analyzed reviews to verify trustworthiness.
I used this coupler for providing flexibility in the joint between two shafts. It works great. Be aware that it fits a 5mm shaft on one side and an 8mm shaft on the other.
