I will say one of the String Lights that I ordered would not take a charge, and Mpowered replaced it. One of my trips though, the last 4-5 of the lights would not light unless I played with the wire leading to the first of the unresponsive lights. I like the string lights, but I don't know if I'd buy again based on my experience.
