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 purchased this to use with some special zipper pulls I had. It works like a dream. The zipper pull went right on and I have been using this bag for almost a month and the zipper glides very smoothly! Definitely will buy more!
