Dear Mina, Hello! First of all, thank you very much for choosing our product and express our sincerest apologies for your unpleasant experience. We attach great importance to the problem you reported. After verification, although your sockets have exceeded the warranty period (purchase time: October 2023), considering your experience, we have reissued the upgraded sockets for you as soon as possible. Unfortunately, our service still does not meet your expectations, and we feel deeply guilty about this. We have contacted you privately, hoping to learn more about the details of the failure so as to thoroughly troubleshoot the problem and improve product quality. If you have other needs, please feel free to contact us directly through +86 18929191223/smarthome@junhao-ltd.com/Alibaba, and we will do our best to help solve it! Thank you again for your supervision and tolerance, and wish you a happy life! Frace
