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 usually ignore requests to review products purchased from Amazon, unless I am exceptionally pleased. This product work great as a mask/cooling cloth when riding a bike or hiking. I soak it in water, wrap it around my face, and tie it at the back. It also works great as a blind-fold while sleeping. Folding it along the long axis to double the thickness blocks most of the light from reaching my eyelids. Lightweight and comfortable. I own several now.
