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.
The insulation on the USB side of this cable has now torn away. I can see the cables underneath, and it was so badly put together that the insulation pulled away in what looks like a clean cut. Two stars, because it still works and is cheap, but I would seriously consider getting another one if at all possible.
EDIT: The insulation on the other end of the cable has now torn away completely. I have had this cable for less than a month.
