I love those long cables! And they arrived just in time! My old cable turned to dust the same day they got here. I don't know if I should really reconsider the shelf life as I've only had it for a few days. But they seem to be of good quality. I think that like most cables, they can break near the connection point if you use your phone a lot while charging (like me), but that's more of a user error issue. i love the length! I can turn over in bed and not worry about unplugging the charger. The price was amazing for 2 cables, one with the bedside table and the other with the sofa for phones, game console controllers etc, very handy! These aren't lighting cords so charge times are average, but since they're so long I don't mind leaving them plugged in while in use.
