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 analyzes reviews to verify trustworthiness.
After I ordered my most recent cords, I went into my Prime account to see how long the last round had lasted. It was over two years in some cases, over three in one. I keep chargers plugged in all over the house, so all of these are getting a fair amount of use (bedside table and home office desk get the most), and none have “died” in less than two years. After wearing out of original manufacturer cords within six months (which are also significantly more expensive), I can’t imagine a better value.
