My husband gave me some of these and my kids keep getting them. I like my cords a little longer. Will have to order differently next time. In terms of durability they are quite thick and my kids use them to charge things in the car and you will be surprised at how much they tear and stretch. Also, they reach the bottom of the truck where they are exposed to dirt, so I'm surprised they can last as long as they do what three boys can do. This is one of the most reliable I've ever had.
