To calculate the overall star rating and percentage breakdown by star, we do not 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.
yes, my wife actually counted a roll and another... and another. 42 rolls yes but each roll consisted of only 15 bags. description stated 20. so I did not get 840 rolls. only 630. otherwise a good product in itself.
