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.
These are a great design, and far better than those plastic tubes with the slice in them that have to be spread apart. The short lengths also allow for sections where different cables head off in different directions. The zipper system makes wrapping around cords and then closure a breeze. Very well thought out.
We got what we needed and were happy to eliminate messy looking cords. The product was well packaged, but actually quite pricey for what it was in the end. One of the zippers split and had to be thrown out. Overall okay, but I would look for a less expensive option.
