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.
I bought a pair of CW-X insulator compression tights about 10 years ago. I still have them and like them very much. The new one I just bought is not as good. Does not have a pocket for my car key and does not keep me as warm. Price has gone up. Quality has gone down. Time to look for something better.
