So I bought this set of 2 in May 2018. I wanted long charging cables for my Samsung Galaxy 7edge. I had surgery and needed a long cord for my room. Also, I wanted a long cord for the hospital. Since there are plugs behind hospital beds it was great to have a 10ft cord! The nurses and technicians were impressed that I hadn't lost my umbilical cord. The cables lasted 11 months. I shorted out a wire while on vacation last week. I had another one as a backup and used this one. I can't believe they lasted me 11 months. The original charger cable for my phone was shorted 5 months after I received my phone. All other cords didn't last more than 1-2 months. Such a good buy! I bought another set to have back in my car and an extra one for when the one in my room finally breaks.
