美国采购需求：电子、照明

I'm reaching out regarding an issue with a wireless wall switch remote control outlet I purchased on April 27. Unfortunately, it has not functioned properly since late July, which has been quite frustrating given its intended convenience. I'd appreciate it if you could assist me with a replacement for the faulty unit. Your support in resolving this matter quickly would be greatly valued, as I rely heavily on this product for my daily use. Looking forward to your prompt response!
