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 looked for this style zipper in 3 stores before I ordered this one. Nobody had the length I needed in the color I needed. It's getting harder to find these locally! But as always, YKK zippers are fantastic, and this one is no exception. It was longer than I needed, but the price was better than local stores, and I just cut it down to size.
